You know, it is "ok" to get their gift to them later or even when they get back from their honeymoon. Don't stress over the quilt. There are too many other things to worry about and I'm sure that they will understand. I have married off 3 daughters in the last 4 years and there was no way that I could work on a quilt during the last weeks before the wedding. The week before we had guests starting to arrive.
