This spacer foam is beautifully soft, thin but not too thin, and flexible. I contains lycra so it has a stretch which you can either use or not use, depending upon your application. It works wonderfully to add that bit of modesty to a bra cup without adding any volume. Use it just like cut and sew foam, butting the edges together in the cup but sewing it into the band. You can add multiple layers if you want to add volume. It's spectacular for the cups of a bralette, especially with a fun print on the band. I have found that it dyes nicely, is usually quite light, and is sometimes not perfectly even. We are still testing it in the new colors.
Spacer foam, like all our fabrics is sold by the half-yard and fat quarter kit cut. It is 45" wide.
