I am a frequent Goodwill (GW Inc) shopper (just walked in the door from there) and I always look for quilt fabrics and supplies. One day I got an unopened bag of QUEEN size batting (JoAnn's sells it) for $1.99. This week I went to JoAnn's to look for batting for my granddaughter's birthday quilt (TWIN size) and it was $11.95 AND I didn't have a coupon! I have found beautiful cottons at GW Inc but I'm never sure how to tell whether it's 100% or cotton/poly blend. Any help with THAT would be appreciated.
