This Saturday and Sunday Stitch London are hosting 'Stitched Science' at The Science Museum in London. There are going to knitted and stitched science specimens on display created by artists/designers from across the globe, you can see some examples of these here. There are also free knitting workshops throughout the weekend - like knit a neuron and pom pom planet rings so if you want to learn to knit this weekend will be a great chance to do that!
If you do pop by have a look out for a knitted aeroplane amongst the stitched science specimens as that's one of mine! - Claire
