I got 1 yard of shirred fabric. I bought it at Walmart for $12.95. I put 2 yards on the supply list so that it covers any size you may make since 1 yard fits a medium
PREWASH!!!! Do not skip this step, wash your fabric BEFORE sewing. It does shrink up a bit.
Wrap it around and stretch till it feels comfortable, either do this yourself and wrap to the front and pin, or have a friend help.
Cut any excess fabric leaving seam allowance of at least 5/8. With 1 yard I got, it to fit perfectly without cutting, (equivalent to size medium) so more or less fabric is needed for small or large
Pin fabric right sides together
Sew with 5/8 seem allowance
Try it on, this was a bit loose do I sewed in another 5/8 then it fit perfect
Cut excess fabric from seem leaving approx 1/4-1/2 inch seem (you can see what's left after cutting in next step)
Iron to set seem (see the clean seem allowance that I cut)
Zig zag stitch the seem allowance to prevent fraying.
Wear your sassy new dress ;)
