I have thought about using a laminator to create my own binder panels, but I thought that the material used would harm the EZ mount cling. This was a while ago that I read about different materials harming cling and polymer acrylic. Some people had problems, some didn't. I can't find the thread where I read all this....and can't remember if it was on the SCS board or another board.
Fiona, how long have you been using laminated sheets and have you had any issues?
What I have done is buy the full sized binder panels from Joann's when they are on sale and free shipping. Then, I cut the full size into half sizes which gives me 10 half size panels. I use binders from Univenture and half pints from We R Memory Keepers (these are retired now....DARN!!).

Yes, you end up with extra holes on the panel, but who cares.
