Well this is it! 7 blocks by 9 blocks (re)arranged in rainbow colours (violet, red, orange, yellow, green, blue, indigo) with sashing in white and cornerstones in two toned complementary colours (yellow, green, blue, purple, red, orange, yellow).
I learnt a lot - mostly that it's a good idea to make all your pieces of cloth the same size if you want them to match up! So, the cornerstones corners don't match with the block corners, but I don't mind so much, and the cat won't care at all!
My difficulty is now that it fits lengthwise nicely, but not quite widthwise as it is, and if I turn it on it's side, it fits well widthwise but is a row out lengthwise. So, do I add two more rows to make it 9 by 9 blocks so it'll fit the bed fully? And if so, what with? Blocks that have coloured backgrounds and white crosses? In the same colourways as the rows? Or do I do a coins border as originally intended?
But if I make it bigger, I don't think I've actually got floorspace big enough to lay it out to back it - it only just fits the lawn now (because of my veg patch and the rotary washing line). But I could solve that by going to the park and laying it out there to pin and tack it, loads of space in Greenwich Park! I just need the heatwave to carry on....
