I ran across this frame on MakerWorld, free download site for 3D printing. I shrunk it down and printed in ‘Copper’ with black rivets and cross members -
The Art was about 200mm square, and the frame pocket about 216mm square. So thin bezel mat on front and a two section mat for the thank you card on the back.
Time to glue and assemble. I sandwiched the art between layers of construction paper matting, so the glue attaching frame and acrylic doesn’t contact it.
Yes, four layers of matting were all cut on the GF -
Black frame around Print (front).
White full layer under print & black mat frame (not shown).
White inset ‘revel’ around thank you card.
Blue face mat around thank you card (Back).
I also used the GF premium subscription (insert shape) to draw, size and cut the matting. Super easy!
