What This Fabric Is
The Shimmer Lagoon 108" Cotton Wideback Fabric, sold by the yard at Linda's, is a 108-inch cotton wideback from Northcott, designed by Deborah Edwards and listed as a Twiggy Wide Backing. Northcott describes its premium wide backing fabrics as offering rich colors, intricate patterns, and a soft, luxurious feel — qualities intended to complement a variety of quilt tops and give a project a seamless, professional finish.
That width is the real story. Standard quilting cotton is usually 44 to 45 inches wide, so backing anything larger than a small throw means piecing panels and living with a seam on the back. At 108 inches across, this fabric can back most quilts in a single piece: no piecing and no center seam for quilting stitches to cross. The Lagoon name suits watery, coastal, or blue-green palettes, but a patterned cotton back also works behind any top where you want the reverse side to look deliberate.
How to Choose a Backing: Start With the Size Math
Use the standard rule before you order: your backing should measure your quilt top plus 8 inches in both directions — 4 extra inches on every side. That overhang gives a longarm quilter room to load, pin, and advance the quilt, and gives a home quilter room to baste, quilt right to the edges, and square up cleanly afterward.
Now run the numbers against a 108-inch width. A throw top at 60 by 72 inches needs a backing of 68 by 80 inches. One width covers the 68-inch side easily, so you only buy for length: 80 inches is just over 2-1/4 yards. A queen top at 90 by 95 inches needs 98 by 103 inches — still inside one 108-inch width, so 3 yards (108 inches of length) covers it in one seamless piece. Only when your top's shorter side plus 8 inches passes 108 inches do you need to think about piecing a backing at all.
Cotton vs. Minky vs. Flannel
Cotton wideback like Shimmer Lagoon is the stable, breathable, all-purpose choice: it presses crisply, feeds evenly, and behaves like the quilting-cotton tops most of us piece. Minky is the plush comfort choice — warm and cuddly, but stretchier, so it needs more care when basting and quilting. Flannel sits between the two: brushed and cozy, warmer than plain cotton, with more shrinkage to plan for. Choose cotton for a predictable finish that works in every season and pairs cleanly with a cotton top and your usual batting.
Working Tips: Folds, Prewashing, and Loading
Pressing the fold: widebacks arrive folded, and crease lines can linger in cotton. Unfold the fabric and let it relax, then press on a cotton setting, working from the center outward. Lift and press rather than dragging the iron, and while you press, check which way the pattern runs so you can orient it the way you want it on the finished quilt.
Prewashing: decide before you cut. If your quilt top fabrics were prewashed, prewashing the backing keeps shrinkage consistent across the finished quilt. If the top was not prewashed, many quilters skip prewashing the backing and let top and back shrink together in the first wash. Either way, press well and re-measure after any washing before squaring the backing to size.
Longarm loading: a seamless wideback loads quickly because there is no piecing seam to center or avoid. Load it straight, confirm the edges are even, and double-check the pattern direction before quilting begins — a directional pattern loaded upside down is only funny after someone else does it.
Care
A finished quilt backed in cotton is made to be used and washed. Wash in cool to warm water on a gentle cycle with similar colors, and tumble dry on low or line dry. Cotton softens a little with each wash while keeping its structure, and rich colors will last longest if the quilt is stored out of harsh, prolonged sunlight. Treat it gently and this backing will keep its soft feel long after the last stitch goes in.
