Goodness, this drives me wild...Beginner class and they want you to do it perfect. Well, how long is that class? Forever? I wonder what the pattern was or was it a sampler? Sometimes things don't fit together perfect so teach them a simple pattern. I did strive to make things perfect when I started and still do but I am not perfect. I'ms sure if someone goes over my quilts with a critical eye they will find something wrong....ie: that color doesn't belong with the others (but I like it), Oh my goodness the points don't match exactly...on and on. I make quilts to enjoy my way. You can teach me the "right" way but many teachers as I've had over the years have told us in classes...sit back and relax. This is what it should look like but we are human. So I put that tweak in an applique piece or turn a corner different from the others..I wanted it that way! Making a quilt is not a race and the "quilt police" can say what they want.
