However when I began to investigate and discovered that these can cost $139 plus shipping my enthusiasm waned until I remembered we [DH and I] had made something similar years ago for the top of an Ikea bureau in my studio.
I think we used MDF cut an inch or two wider and deeper, then attached cleats to front and both sides
You can see that there are two pieces of wood positioned to hug the narrow end of the board.
I am very pleased with this, probably took less than an hour total time.
It's every bit as good as anything I could have purchased and all for about $30. I used two layers of 100% cotton batting and the 100% cotton aluminum coated ironing fabric from Joann's.
The Oliso iron here is one I purchased at "Tuesday Morning" a few years ago for around $50. Until recently I had used it very little but once I began to use it regularly it has become my favorite - only a quilter would have so many irons! If you ever watch the Missouri Quilt Company videos you will notice that they use an Oliso iron.
