If your Walmart has a fabric department
Check to see when they are having their fabric sale. I was in the local store today, browsing the fabric, and the lady who works there told me that they are having their big fabric sale next week, Thursday through Saturday.
The last time I went to one of those it was NOT their better fabric. It was more like the stuff on the $2 a yard table, but lots of it. I can't remember what it was priced last year to know if it was a bargain or just the usual $2.
