My cutting mat warped in the car on Saturday afternoon after being left for only 30 minutes as I ran into a store. I found a link in this post that really helped with the problem. Most of the warp is gone it clouded up and rained after the mat had been outside for only an hour so Ill put it out again on the next sunny day. I put the plywood on my deck. (DH thought I was crazy for using the glass top on our end table but it worked!)
Fixing a Warped Mat
My German-made and not cheap Rowenta iron started to leak water through the steam holes when the water level dropped to a certain point in the tank. Look at the last post from Christine- for instructions on cleaning irons with vinegar. No more leaking.
