I have been sewing for over 40 years.. and quilting almost as long... since clothing sewing clothes always produced scraps. I concider myself a confident quilter.. but there are still times .. all the stars just did not allign right .. and I make silly mistakes. What I have learned is to forgive myself and move on. Perfection is a judgement call... and this quilter finds that kind of pressure takes alot of the fun out of it. Learn and grow, mistakes or things that could have been done better are lessons learned not something to retreat from.
