When you do hand piecing, you do not stitch into the seam allowance, and when it comes time to press there is no real obvious way to do it. I look at how the fabric and pieces want to go, and kind of follow the natural lay. You will see there are some over and unders on the back here.
The Karen Kay Buckley medium size 6" scissors are the perfect size for cutting out these small pieces of fabric. They have a micro-serrated edge, which helps to minimise the fraying
If you want to do some hand piecing, and you live in the Adelaide area, or visiting, come to Hettie's Patch on the 1st Saturday of the month (not January). Sit around the table and do some sewing. I will show you the tricks to make it easy and fast. Ring the shop to book your seat.(08) 8346 0548.
