I recently purchased a well known manufactures charm pack, thinking it was a good way to get the variety without going to many shops and having to purchase more fabric than I needed ( many shops have a minimum that will cut). Even though I broke my rule of not buying because of cutting variances... I did it any way... well back to my rule of not buying precuts. The charms were off 1/4 inch on one side... so much for a fast easy project. I hade to recut and the pattern I had my heart set on was to use every bit of the 5 inch square.
