It's not something I PLAN to do, but it comes with the territory. Fabric is stretchy so seams can become wonky. Fabric has two sides so the wrong sides can be sewn together. Quilts often use patterns so it is easy to pick up the pattern out of order. Ripping (or frogging as many call it) is just part of the process. Nothing to put extra emphasis on or beat myself up for. The faster I can undo the mistake, the faster I can get moving forward again.
