Sounds like all good ideas to me! I have been sewing and quilting for a long time! there are lots of different ways to fix things! Amish quilts have built in "Mistakes" they tell me..I have used most of the suggestions given previously..
All of my quilts have had mistakes in them..I try to cut pieces exactly and sew seams exactly but sometimes it just happens! I quite quilting for a while, then I saw quilts in shows that I examined (beautiful but) looking closely they were not perfect either. Each quilt teaches me something new! We really don't make mistakes just learning adventures that bring new ideas into designs! Happy accidents!
