I have been using some Amazon purchased Baltic Birch, that is about 3mm or 1/8" thick. I am not really that happy with it. Just about everything I have cut with it larger than a few inches (25-30 mm) ends up with serious warping. I have not had any warping problems with the PG draftboard, but I know that’s just MDF.
The BB plywood seems fine for really small things like earrings (which is good, because I still have probably 15 sheets), but not for anything larger. I was surprised it warps so much. My basement, where I have the GF, is about 60% humidity year round (at least until the dead of winter, when it might drop to 30-40%). That may have something to do with it.
I haven’t really experimented much because I didn’t want to order a bunch of material until I had some practice, and I feel like I’m at that point now. My GF only came with two different types of wood- draftboard and medium basswood plywood. I haven’t tried the basswood plywood yet.
Just looking for some more info on what your “goto” general purpose material is, ideally 1/8". I am going to be traveling off and on over the next two weeks, so I could probably put an order in to GF for PG materials, but I’d also like to know if there is a good supplier on Amazon that’s worth getting. I hear a lot about “Woodchucks” but haven’t tried their stuff yet.
My next project is to cut some turkey napkin rings for Thanksgiving. They are fairly good size, maybe 3" or so wide by 2" high. I am still tweaking the design so the engraving turns out how I like it. It turned out pretty well on the draftboard, and I could use that, but I don’t know if I have enough to complete the project (probably need about 30 or so of them). I think my BB plywood is going to warp too much to use.
Thanks in advance!
