Hi, I want to crochet my own cardigan (for the first time!) but I don’t know which and where to find the perfect yarn for it :<
I only want to spend at most 10£ on yarn , as I can’t spend a lot of money 
I am not 100% sure on how much yarn I need, but if anyone can help me figure that out too, that would be very helpful! I usually buy from the women’s section tops size XS, and I am planning to make a patchwork cardigan (exactly like this one! )
I want to use these 3 colours (doesn’t have to be 100% the same) and the dark green for the trimming :
I prefer Aran size yarn, and I don’t mind any material for the yarn! I can buy from websites or from local stores!
Sorry for writing too much and being too specific 
but I appreciate any response!
