Comic Book Speech Bubble Drop in Frame

Specialty frame that can hold your cross-stitch, needlepoint, embroidery or other art!

Frame opening for display (roughly)-8.5" x 6.8"
"Art slot" interior (roughly)-9" x 7.25" x .25"

It was designed around a specific counted cross-stitch piece, and in the future I'd like to make more standard sizing options. When centering art in the opening, it's not perfectly vertically center. You'll want to mount it slightly off-center down by an 1/8 to 1/4 of an inch. Hopefully I can solve that in future iterations.
Despite being a professional drafter at one point, this is my first big product design so all feedback welcome!
