If you happen to be going near one for other reasons, you will probably want to check it out, but meanwhile you can go to their website
http://www.joann.com/joann/home/home...opnavlink=true and see a pretty good sampling.
They have a lot of crafts, yarn, and some seasonal decor and organizing supplies, but also a pretty good selection of fabrics of all types. They are known for sending out excellent coupons, and you can get those by e-mail by signing up on the website. The coupons are good online, at least part of the time. I usually don't want to pay postage, but ordered yarn from them one time a couple of years ago and it came promptly.
