Reply to comment by MaybeYouHaveAPoint in Could you tell me your opinion about sizing for this simple wooden frame for a plexiglass window? by MaybeYouHaveAPoint

Make the cross out of 2x2 and lap join it in the center. Then nail trim to all the inside faces on one side, insert glass, repeat trim on the other side.

Oh and when I say trim, doesn't have to be fancy trim, you could just rip your own square trim from scraps on the table saw. It's just a shed afterall.

Seal the plexiglass to the trim with a thin bead of clear silicone and it won't rattle and eliminate any drafts

Yeah, I'll sketch it out and maybe try that, thanks.

Traditional windows this size would use a nominal 2x2 muntin but with a profile done on a shaper. They would not be dadoed and built around the plexi becasue that way you can't replace the panes; they use a rabbet and stop or putty instead. The vertical of the cross gets a 90 degree notch both sides, as does each inner edge of the outer frame where it meets the ends of the "cross." The ends of the cross are pointed 45 degrees each side to register in the four notches. It's a very strong construction, simple on a tablesaw.
