I also made a board from a piece of wood that Home Depot cut for me. I first stapled a large plastic garbage bag (out door leaf kind is large enough). I did this to keep the steam and moisture from getting into the wood because it will warp if there is not a barrier to keep the steam out. Be careful ironing on your table. I bought one of these ironing pads and used it on top of a sewing cabinet that I was not currently using. Several months later, I needed to use the machine and I took the pad off and the top of the cabinet was ruined...yep learned the hard way. Even the professional boards are not that good. I have laid my home made board on a plastic topped table, counter top and even a bed and I have never had issues with the steam or heat going through. Hope this helps.

I have a large ironing pad that I use on my dining room table. On occasion I have placed a quilt on a bed. I always iron the quilt top carefully on my larger ironing board, but only small portions of a quilted quilt, on areas that were creased from being rolled on the quilt frame. A quick spritz and 10 minutes in the dryer on fluff air, usually takes care of minor wrinkles. Good luck!

I iron my quilts every step of making them. Its not often they ever need ironing, everything been ironed already.

My husband made me a wood cover for my ironing board. He used quarter round and outlined the original board, then attached it to the wood board. Now I can slip it on or off. I made a square cover and used batting for padding.
You can also buy these but they are expensive.
