WOW I am so jealous of this beautiful sewing room. WOW I would live in there. LOL I would probably sew and sew and never come out. Beautiful. I do agree with the others on the peg board, and I may be wrong but it looks in the picture that the top piece is flat against the wall and the second lower piece bows out a little to accomodate the tiles, that would cause the problems. Now, I am wondering if you can take one of your rulers, put it in warm oven, very very low and warm it up and then lay it flat and put something heavy on it until it cools and then it would be back to normal?? Wish I had a DH to do such a nice thing for me. :-) You are very very lucky. Again, it's beautiful
