With the loss of Joann Fabrics (flashbacks to when Hancock Fabrics closed down), we need new sources to acquire supplies. So, with the help of others and some digging on my own, we have a list. It will be updated as we find good links and recommendations. With no further ado, here's a list for fabric and yarn, with both online and local ideas for you.
Online Fabric Stores
Online Yarn Stores
Crochet, Weaving, and Knitting Yarn | BLICK Art Materials
Notions/Finishings
In Person/Local Possibilities
Walmart
Hobby Lobby
Michael’s
FB Marketplace
Goodwill/Thrift
Yard Sales
Local buy nothing groups
Herrshner's is a good source for yarn, and they have shipping discounts on a regular basis. I've been seeing a ton of fabric websites, and will let you know what I find.
