How do you flatten cross stitch fabric without an iron?
Lay out a soft bath or hand towel (depending on how large your piece is), and lay the fabric face-down on the towel. Smooth out any wrinkles and then place another towel on top. Roll the towels up like a jelly roll with the stitched piece in the middle.
How do you finish Aida edges?
You can overcast the edges with a simple whip stitch, or fold over the edge into a hem and baste it. When hand stitching the edge, use regular sewing thread doubled up. Be sure to stitch into the fabric a bit so you don’t end up pulling up the edges – 1/4 to 1/2 inch should work.
