!/4 inch seams, 1/4 inch seams, and 1/4 inch seams. Over and over and over till we get them right. This one thing is so importaant, and when we forget to do it, the whole quilt is messed up - wavey edges, puckery piecing, points that don't match, and we spend way too much tie with our 'favorite' tool doing the frog march. Teach that it's smarter to sew slowly. Piecing a quilt is not a race to see who finishes first. I make many more mistakes when I 'step on the gas than when I sew slowlly but sweetly! As soon as I put pressure on myself to 'get the done,' I'm going to be in trouble.
