Orc - good to see this progressing.
The plastic grids you have are very similar to grids they use in either embroidery or canvas work.
Mine were sold by Hobby Craft in the UK and manufactured by Darice look at
www.darice.com. They are called Canvas Designer - plastic shapes, Malla Plastica, Formes de Plastique.
I got 10 x 4" squares for not a lot of money, sorry can't remember how much - the grid can be bought in a variety of sizes. If I can post a pic it will be here.
