Thanks all. Purple we aren't in at the moment, but if last year is anything to go by, it is very possible that we will be in again through the autumn/winter as she is immuno-suppressed and picks up everything. I was sewing little felt baubles when we were in last year just before Christmas. The teenage cancer unit has the best selection of crafty bits, and the lovely lady who works there was pleased to have some people up for a bit of crafting! I will deffo be taking crochet with me, should we end up in again. DD ends up bored too, especially if she gets isolated, so I will teach her too. 
aJumped YY to crispy fingers! Wolf I started at 5.30pm this evening (on my Saturday munchy night) and have only just stopped now, 4.5hrs later, to have some mango. I feel all virtuous

I'm down to the last dozen to do, then I have to put it all together. I'm starting to regret not having a pattern in mind, as I suspect trying to organise 2 colour squares in 13 colours is going to be a bigger challenge than what I originally imagined...
