20 Pack White Foam Board 12" x 16.5", 3/16" Thickness Foam Core Baking Board for Projects, A3 Polystyrene Mat Board Poster Foam Board Sheets for Art Crafts, Presentation, Wedding, School Projects | Sturdy Polystyrene Backing Boards, Lightweight Poster Board for Art Projects, Presentations, School Displays & Wedding Decor

Worked great making signs for a wedding. I could use my cut vinyl and take off if I messed up without tearing the board.

I use this for backing my diamond paintings

Great to keep on hand for crafts or extra bulletin options!

I use these to cut out wreath attachments for wreaths. Then cover it with material. Great quality. Good thickness. I bought white but it comes in other colors.Easy to use and would recommend.

Great value to supply my classroom, but quality could be better.

they were the perfect size, just what we needed.

Not sure how it's gonna hold up- I used a spray adhesive to mount uart paper on, and the adhesive seemed to eat into the foam- my mistake- but the foam doesn't seem as rigid as it should be- but i have yet to compare to something like gator board which i think is a much smaller celled foam- I do however have several pastel paintings mounted to this foam and it is workign well- but you have to be really careful as it dents easily, and won't look good is you should happen to sell your work- however, you can perhaps paste a heavy paper on the back of the board to prevent it from denting- This foam is a little hard to cut as the cells inside are larger, and tend to not cut the cleanest- it leaves a bit of a ragged edge- but these will all be behind a frame and not noticed- over all=- i woudl recommend this if you are mostly practicing pastel painting, and want something not so expensive to mount them to

We used these boards for a 2026 vision board party. They worked great!
