The squared background print that will be part of the final design is the guideline for sticking on the squares, ensuring each on has a slight gap between to allow for sewing space.
I started off wanting to make a whole apron but it has turned out to be more of a pouch that could possibly be attached to an apron with poppers/ribbon.
I bent 3 laminated pieces of ply into a slight curved shape in the vacuum packing machine. I then glued this onto the fabric between two areas of plywood squares. The next stage is to cover it with another piece of fabric and machine stitch between the squares.
