Having made a fair sized pile of my little bricks it felt like time today to play around a bit and try out options for 'mortar' to join them together. And that is where it all went horribly wrong. I had envisaged using my blue fabrics but when I looked at this properly it so clearly was not going to work. Here's a sample.
See how absolutely unsuccessful this is? The background is too busy and the squares don't stand out enough; really not what I was aiming for. So back to the drawing board. I still want to use the blues, but will think about other ways of incorporating them. Maybe they will be bricks too.
In the meantime I'm looking at more neutral fabrics - I've got a couple of grunge ones that might do: a very pale blue and this dirty cream colour.
