The cloth that only appears for a gathering usually has the most decoration on it. A runner down the middle of the table. An apron worn for one long afternoon of cooking. A dress that has been sitting in the closet since the last round of parties. A good share of them are finished with a flat zigzag braid stitched down the middle. Wash any of those once and the edge can come back rippled, with the braid standing in little waves and the cloth gathered up between them. Nothing tore and nothing came unstitched. Two materials simply stopped agreeing about how long they were.<\/p>\n

\"Rickrack<\/figure>\n

What Rickrack Is and How It Sits<\/h2>\n

Rickrack trim is a narrow braid woven as one continuous zigzag, with both long edges finished in the weaving so it never needs hemming. It comes in cotton, cotton blends and polyester. The thing that separates it from a flat tape is that it is already wavy along its length, which means it can follow a curve without anybody having to ease it in or clip it.<\/p>\n

It is attached in one of two ways. Either it is topstitched flat with a single line of stitching straight down the center of the braid, or it is laid into a seam so only the points stick out past the finished edge. In both cases the stitching holds the middle of the braid and nothing holds the points. They are free to lift on either side.<\/p>\n

That is why it gets used. One pass of stitching gives a line of contrast and a scalloped edge at the same time, the braid does not fray when it is cut, and it bends around a curved hem that a straight tape would fight. For a table runner or an apron it is about the most practical decoration there is, which is why so much household cloth carries it.<\/p>\n

The mechanical result of being anchored only along the center is worth holding onto, because both of the trim’s problems come from it. Across the stitching line the braid is considerably stiffer than the cloth it is sewn to. Either side of that line it is loose. A stiff, loose, unattached edge in a machine full of moving water behaves very differently from the fabric around it.<\/p>\n

Two Materials, Two Shrinkage Rates<\/h2>\n

Woven cloth shrinks the first time it is washed because of what happened to it before you ever saw it. Yarns are held under tension through weaving and finishing, which pulls their natural crimp out and leaves them straighter than they want to be. Water lets them relax and crimp back, and the fabric takes up less length than it did. The braid relaxes by its own amount, set by its own fiber and its own construction.<\/p>\n

Nobody matched those two amounts, and the mismatch has to go somewhere. If the ground fabric relaxes more than the braid, the cloth is now shorter along the stitching while the braid still measures what it always did, so the surplus braid rises into waves. If the braid relaxes more, it pulls the cloth in and the fabric gathers along the line. Both come out looking like a pucker.<\/p>\n

Some combinations are reliably worse. A cotton braid on a polyester ground, where only one of them moves. A polyester braid on a cotton ground, where the same thing happens in reverse. Older trim that was never preshrunk at all. And any braid applied along a curved or bias edge, where the cloth has give in it and the stitched line of the braid has none.<\/p>\n

Why the Pucker Sets and Stays<\/h2>\n

A pucker becomes permanent the same way a crease does. Cotton and linen fibers hold whatever shape they are in when they dry, because the weak bonds inside the fiber break in water and reform in the new position. A rippled hem that goes into a dryer rippled comes out with that ripple set into the fiber, and from then on it is not a wrinkle to be smoothed but a shape to be argued with.<\/p>\n

Heat makes the worst version of this. On a cotton braid, hot drying sets the wave hard but steam and patience can still move it. On a polyester braid, heat can deform the braid itself, and a wave heat set into a synthetic is not coming out at any temperature you would put near a garment. That is the one genuinely irreversible outcome, and it is caused entirely by the dryer rather than the wash.<\/p>\n

Which means the order of operations matters more than anything else here. Both materials are going to reach their new lengths. The only question is whether they do it while you can still influence the shape or after it has set. Taking the item out damp, laying it flat, and easing the fullness along the stitching with a flat hand is the whole technique.<\/p>\n

The Free Points Catch Things<\/h2>\n

Because only the center line is stitched, the points stand slightly off the cloth, and a drum is full of things for them to hook on. Zipper teeth, bra closures, button shanks, the metal end of a strap. Once a point is caught, the drum keeps turning and the pull has to go somewhere. What gives is either the point of the braid or a short run of the center stitching, and both show.<\/p>\n

Color is the other drum problem. Bright rickrack trim on a pale ground is often a saturated color, and saturated colors in warm water are the ones most likely to release dye into the wash and put it somewhere unwelcome. The first wash of a newly trimmed piece is the one to run on its own and cool, which also happens to be the right way to handle the shrinkage.<\/p>\n

The rest is just reducing opportunity. A mesh bag keeps the points away from hardware. Turning the item inside out faces them inward. Cool water, a short gentle cycle, and a load with nothing metal in it take most of the risk out of a wash that would otherwise be fine nine times and ruinous the tenth.<\/p>\n

Washing It Without Rippling the Hem<\/h2>\n

Treat the first wash as the one that counts. Cool water, alone or in a mesh bag, on the shortest gentle cycle available. The relaxing that both materials are going to do will happen once, and you want it happening in cool water with the item able to move freely rather than halfway through a warm cycle buried under a load of towels.<\/p>\n

Then dry it flat. Take it out damp, lay it on a towel, straighten the edge, and run a flat hand along the stitching line to spread the fullness out rather than letting it bunch in one place. Do not hang it by the trimmed edge, because wet cloth is heavy and the braid ends up carrying the weight of the whole piece. If a dryer has to be used, the lowest heat and out while still damp.<\/p>\n

Pressing is a reverse side job. Work from the back with the tip of the iron traveling along the stitching, using steam and very light pressure, easing fullness outward toward the edge instead of flattening the braid. Keep the iron cool if the braid is synthetic, because a glazed braid stays glazed. And be honest about the result: some ripple normally stays, and on a well used apron that is simply what the piece looks like now.<\/p>\n

Humid Air and Trimmed Cloth in Jacksonville<\/h2>\n

This part of the year is when the trimmed pieces earn their keep. The runner goes on the table, the apron gets worn through several long afternoons in a row, and then all of it goes into the wash together because the house is busy and nobody is sorting by decoration. That is the point at which a hem that had been fine for years comes out with a wave in it.<\/p>\n

Jacksonville air is the complication. Humidity runs high enough that something laid flat indoors can stay damp for a long stretch, and a damp flat item is exactly the thing people give up on and put in the dryer. A rack with air moving on both faces, or a fan pointed at the piece, solves it without heat. Leaving a damp trimmed item folded in a closed bin solves nothing and tends to leave a stale smell.<\/p>\n

The timing habit that helps most is to wash anything newly trimmed well before the season gets busy. Let the shrinkage happen on a quiet afternoon when there is time to dry the piece flat and ease the edge out by hand. Doing it the night before a gathering means drying it the one way that sets the ripple permanently.<\/p>\n

Trimmed Pieces at the Laundry<\/h2>\n

Decorated cloth wants a cool cycle, a bag, and a drum with nothing hard in it. A bank of washers in different sizes means a runner and an apron can go in on their own rather than riding along with a load full of zippers, and dryers with low settings make it easy to stop while the piece is still damp.<\/p>\n

The machines at our self-service laundry on McDuff Avenue South<\/a> give a trimmed piece a small cool load of its own with no hardware in it, and let you pull it out damp so the edge can be laid flat and eased straight by hand before anything has a chance to dry into a wave.<\/p>\n

Our machines and the store are cleaned daily.<\/p>\n

Nou wash-dry-fold service<\/a> covers the everyday laundry.<\/p>\n

The short version<\/h2>\n

Rickrack is a woven zigzag braid held by a single line of stitching down its center, which leaves its points loose and makes it stiffer than the cloth across the seam. The braid and the fabric relax by different amounts in the first wash, and the difference shows up as a pucker. Wash cool, alone or bagged, with nothing metal in the load. Dry flat and ease the fullness out by hand. Keep heat away from a synthetic braid entirely.<\/p>\n
