I've been playing with my charm packs. Opened up my 2 Moda Kansas Trouble Flannel and wasn't too happy.
I had to go through and square them all. Luckily they were on the bigger size but still-not precision cut at all. Some of the corners were cut in so I'll be a little short on some seams. My cottons I used earlier were a little off also but no need to square them.
