Must. stop. buying. fabric.
Often you'll hear that the reason knitters have such a huge stash of sock yarn is because most of the time you only need to purchase a single ball to make a pair of socks and it's "usually" under $20.00. So it doesn't seem like a huge expense. Ha. Sock yarn doesn't have a thing on fat quarters.
For the non-quilters in the crowd, a fat quarter is a piece of fabric measuring 18" X 22" or ... a quarter of a yard. And these delightful little pieces of fabric can be had for as low as $2.00 on the ol' Innernets. Of course you can't exactly make a quilt out of one fat quarter but if you piece a whole bunch of 'em together, well there ya go. Or you can make little things. Like gift card holders.
The yarn store I work at is very big on promoting environmentally friendly knitting options. We also sell reusable gift cards at the store. What better way to stash your reusable gift card then in a reusable gift card holder? I know, I know, I'm a genius. Actually, if the truth be known, I just like making these little wallets so I'm trying to think up as many uses for them as I can. And I can use up my stash to make them. Err, that would be the "old" stash. As opposed to the "new 2008 stash."
