I'm having trouble appliqueing corners of 2" squares. How do I fold in the corner. Which way do I fold it so the raw edge dosen't show. I'm folding it under 1/4" and basting around. But one edge of the fold still shows and I'm in need of some instruction on a folding technique so no edge shows and I can do hidden stitiches or hidden as much as I can. It's been years since I picked up a needle and done tiny stitches. Help! Help!
