No, I think Popsicle sticks describes what you are using. Sorry I sidetracked.
I used the remnants of an old piece of plywood furniture which had been covering a hole in the fence when we bought our house 20 years ago and the layers of ply, which I cut into strips, were about the same thickness as a Popsicle stick. As everyone has said you need to put weight on them as they dry - I think I used PVA glue and left the weight on for a couple of days. This was about 8 or more years ago and they are still sitting nicely (mostly)
Have you finished yours yet?
