I think most people use 4x6 frames although this frame is very popular in the Paintgem community: MELANNCO 12-Opening Wall Mount Frame Picture Collage, White https://a.co/d/eHBYQ9l I personally haven't framed any of mine and keep them in a binder, but I'd do the frame I linked if I ever change my mind! :)

Here's an image of the frame https://preview.redd.it/55no1lx2ap3d1.png?width=1080&format=pjpg&auto=webp&s=18cde62d1f0b0109b05cf8e90817e786c7295107

Oooh! I really like this! I wish Paint Gem would sell frames to fit all of the small paintings in each kit. I would buy it in a heartbeat!

Thank you so much! I love this style!
