Take this from someone who has made 5 of DWR. If the puckers bother uou that much turn the backside to you and make a few tiny clip from outside edge of the oval towards the inside edge. Stop before you come to that seam. It should ease enough that when you press it the puckers will ease . Its not the end of the world. I gave my first one to my Dh for our 25th Wedding ann. We still sue it and we are going on 57 years. I made one for each of our children when they married.This is the hardest pattern I think there is to make. Good luck with that tiny pucker.
