I just made some more. I used a piece of plywood and stapled an industrial strength garbage bag on first wrapping it around the board on the rough side. I then stapled a piece of batting around and then a piece of canvas. I try to make them tight. The canvas will looked like it has wrinkles in it. Then I take a spray bottle and spray it several times until it shrinks and is tight. It takes about 20 minutes to make one and my husband does the stapling for me. I put it on my cutting table and then put my cutting mat on one end unless I am ironing a large piece of fabric. Then I take the cutting mat off. I also made two a smaller ones for classes and one for my niece and sister. I also made a cover bag out of muslin so I don't ruin the canvas with scorching or ironing with starch. I have been using one for about 3 years. The new one is for our vacation home in NC. Just get it all ready and then call the husband. Home Depot will cut the wood. I leave the smooth edge out so I don't get splinters. Hope this helps.
