A very handy item to have.
Years ago I had this made and it has seen many many projects.
The odd shape is because originally it was nailed to the side of an old desk that I used as a sewing table.
An old blanket glued to a piece of plywood.
Just the right size for a quilt block and the iron.
For when I use the stitch n flip method for crazy quilt blocks.
Its also a good firm surface for heat transferring embroidery patterns.As I find the ironing board too soft.
I would thoroughly recommend getting your own.
