I’m going to make this topic a wiki. This way we can share vendors that sell material locally.
- P&K Custom Acrylics - Sells scraps/cutoffs
https://pkcustomacrylics.com/ - 40 Faulkner Street, Malden, MA
- Altec Plastics - Has a retail operation for small quantities.
https://altecplastics.com/ - 116 B St, Boston, MA 02127 (N.B. hours are 8a-4p M-F)
- Industrial Plastic - No website. 9 presidential way, woburn ma, 781-938-6600
has a ton of scrap, and they are quite reasonable. [Edited 9/19 - just called, they had no scrap. They may at other times, but they didn’t make it sound like something they deal with on the regular.]
- Rockler, store locations by state: http://www.rockler.com/retail/stores
- Boulter Plywood, Somerville: http://boulterplywood.com/ - nice cabinet-grade ply.
- Woodcraft of Boston, Woburn, 185 New Boston St, Woburn, MA 01801, (781) 935-6414 A bit pricey and selection is iffy, but they have some thin boards, as well as pen blanks (wood & acrylic), plus tons of stains and other finishes.
