I first try to get a photo outside immediately after finishing the quilt. I think the pattern and fabric show up better in pictures before the crinkled look. And of course, being outside, it will get something on it, no matter how careful I am.
Then I wash mine in either Dreft or Arm & Hammer Free. Dry without sheet. Then I check for flaws and snip loose threads. Next I iron it as flat as possible and gift wrap. Usually the party is 10 minutes after I finish wrapping it, LOL. I try to include a little note with the quilt saying it's been washed, the crinkled look is normal, and it's brand new, specially made for them.
