Wow! That's a truly beautiful quilt, mommessy!
ntroxel,
If the recipient plans to wash the quilt, I would also recommend using a Fabric Medium. They sell Golden brand at (
http://www.dickblick.com/products/go...fabric-medium/) that is just a tiny bit nicer than the brand they sell at HL -- but either one works fine. The Fabric Medium will permanently set any ink that isn't water soluble. I just brush it on with an acrylic brush, let it set for a week & then pop it in the washer on cold, handwash cycle with a tablespoon of Tide Free. Once it's been washed, there is an almost indiscernible difference in the hand of the fabric versus non-treated fabric. After washing, I wet block it.
It's more work than just using plain marker with no treatment, but then you can be virtually assured that the ink will not fade, change color, bleed, crock, or wash out if ever laundered. If you have any extraneous ink marks, be sure to remove those prior to using the fabric medium or it will permanently set them.
