K-Roll, hope you have fun. Yes, having the right ruler is definitely a god send when cutting the blocks. But, don't be so hard on yourself. We ALL cut blocks wrong from time to time. You'll get better and more confident as you go along.
Deecee, Hope you feel better soon. Yes, when I begin to start sewing things wrong, I definitely put on hold also. No sense ruining the fabric by ripping, ripping, ripping. I took a simple block apart yesterday 3 x's. But, later in the day, I put together a block that was more complex and it only took one try. Go figure, right?!
