As I was shopping at Walmart I decided to check out their fabric department, boy was I surprised to find some Gorgeous knit fabric and here is the kicker it was....$1 a yard!!!!
The floral isn't knit fabric but the rest are! I bought several yards of each, usually I only buy a yard but it was soooo cheap I bought a lot more!
You want to know another cheap source of fabric? Sheets.
These ones at my Walmart are $4.97 I bought this to back a little quilt I have been working on. It isn't 100% cotton but I thought it still felt good for what I needed it for. The twin sheets are the best bang for you buck because the next size is $9.97 and you only get a little bit more fabric.
