Bed sheet for sewing projects? How cost effective is just buying bed sheets to use for sewing clothes? A twin bedsheet set with fitted sheet and flatsheet is four yards and some. I've seen good enough quality ones for $15. A similar fabric from Joann's is usually $7/yard, sometimes $5/yard. So at Joann's I'd be paying $20-$28 for the same amount of fabric and quality as I could find in cotton bedsheets. It's not a huge savings, but enough that it makes me want to buy sheets for any project that calls for light cotton. Not sure if my calculations are way off - I'm still trying to get the feel of how much I should be paying for fabric. Would love to hear from people who have a lot of experience with sourcing their fabric and understanding pricing and quality!
