Thank you all for your posts! This board is so friendly and helpful. I've learned so much in just the couple of weeks I've been reading here.
While the kids napped this afternoon I steam pressed the borders then laid it out with the backing and batting. Actually got the basting done while the kids still slept. (They took a fabulous nap today!) I was happy with how much of the wave was pulled out just with the basting. I'll do a little extra quilting in the big border and hopefully it won't be too noticable when all is said and done.
