*I’m in no way recommending this place yet since I’ve only just placed an order and haven’t seen any examples of their wares.
I found this Falken* place last night when I was looking for transparent yellow 1/8" acrylic. Their selection seems good, especially in the fact that, for each color, they offer variable levels of transparency. The pricing seems decent enough at ~$9 for a 12" x 12" sheet. So I ordered a few sheets and we’ll see what happens!
I ordered from Inventables and http://ocoochhardwoods.com/ already. That’s acrylic, engraveable 2 color acrylic, MDF, “Fun Foam” and Hardwood/Ply. The black stuff in the middIe is scrap from some other projects. Not really for the , but it might engrave. I ordered most of this stuff about the time I made this T-shirt:
12"x12" yellow transparent acrylic is $3.99 from estreetplastics.com (my regular supplier)
The shipping is a bit high if you order small amounts though.
1 would cost $12.40 with shipping but if you bought 10, they would only be $4.99 each with shipping
If my local sign shops dont have what I need (they sell scrap cheaply), I go to their source which is Piedmont Plastics. I buy a lot of different things from them like PETG, sintra, acrylic etc. They generally come in 4’x8’ sheets.
