I have a blank quilt block to design for a friendship quilt. Any simple ideas-cross stitch, embroidery, etc?

If you've done needlework before, you can transfer any image to the blank block and then outline stitch it. You can draw your own, or just write a message even. If you aren't into needlework, you can decorate the block with sewn or glued on beads, ons, lace, etc. You can even just draw right on your block. If you do this, be sure to use the right markers. You need pigment markers that are permanent when they are heat set. Do NOT use Sharpies - they bleed into the fabric. I recommend getting another scrap of fabric to practice on. Iron a piece of freezer paper to the back of your fabric to keep it from scrunching as you write on it.
