as shown below. It is already painted white and has some fabric that I added over the back.
I used a ruler to draw my monogram since ours is so simple. You could also print a letter from the printer and trace it onto your fabric.
Then is it sort of like working a puzzle. Add in pieces of sea glass here and there until you have completely filled your monogram. I layered the sea glass on top of one another for a three dimensional effect as well. I used hot glue to attach my sea glass pieces.
Once your monogram is filled completely with sea glass, just add it to your shadowbox for a fun addition to your beach themed decor. Don’t hide your sea glass collection away in a box. Display it with my sea glass monogram craft.
