You may be right. I used to cut sheets of glassine into strips, but in more recent years I buy the glassine paper rolls (40mm width) from Bioquip. Just cut the strip as needed; you can reuse each piece a few times. Much better than ordinary paper, which causes a lot of scale removal.
Just finished making my new spreading boards: 15 flat with various sizes and 2 angled, total cost $5.00+2.5hrs of labour. Yes, I know labour hrs are expensive but in my case I have too much of free time on my hand.
I-use a table saw, i just cut strips and then cut a groove. Then I use a thin panel of wood and glue it to the bottom. The panel of wood is a personal preference. Then if there are any rough edges I use an old concrete trowel and a concrete edger which I hear with a torch to smoothen the sides. It ends up taking me less than half an hour. For lyncaenidae and small leps I only use my homemade balsa wood boards.
In re: longevity of wooden boards -- I have several which I have used for well over 20 years. Every few years I lightly sand the boards, and they return to a very nice smoothness. The bottom of the groove is lined with plastazote pinning material, which appears to never wear out.
