My sock collection (first batch) has been growing quite a bit these last few days. Yesterday evening I had done 8 small ones and 9 medium ones. I have tried to vary them, different yarn combinations, different patterns and I bought three colours that I haven't used yet (they will be my next medium one).

new colours

So because there are still many socks to be done and I can't ask my kids what colours I should mix (I am trying to make this a surprise -  how that is supposed to work when they can see me knit all the time I don't know, but I can hope ;-) I wanted to ask YOU what I should knit next.

second batch

There are two sizes to choose from: S/M
There are a lot of colours to choose from: white, grey, black, yellow, orange, red, pink, purple, lilac, turquoise, royal blue, smoke blue, light olive green, dark olive green, fir-tree green
There are also the different patterns I already tried or you can wish for a new one (if it's doable ;-)

So what would YOU like to see or which one should I knit again (I can have twins because the socks are for two kids)
