What kind of batting did you use? If it was anything other than poly you will not be able to press the puckers out because your batting shrunk and gave the well used look to your washed quilt. Additionally 100% cotton thread also has a bit of shrinkage causing these small wrinkles along your quilting stitches. Personally I like this look. Give the quilt with all the love you intended. My view is it is better to give the quilt washed so any changes in appearance are already there and the intended recipient does not think they "ruined" it or did something wrong after their first washing.
