Here are a few pics.
I assume you wanted to see the back side of mine...
I lowered the ironing board to the floor for the second one. just to be able to get a top view but I'm sure you all can get the idea of it.
For me, since space is an issue, I cut my plywood at 18"x48. I was able to get the half sheet of plywood from Home Depot and I gave the other half to a friend months ago. She never did make hers...
But.... it works for me. I like it a lot. If I had more room, I would have loved one bigger but I think it's just right. I also keep a table top one I got from Ikea for like $3 or so a few years back. That one sits by my cutting table while I'm in my craft room - I don't have room for my big ironing board in the craft room...
