I'm crocheting lots of squares with quite bright colours, mostly shades of blue, purple, pink, green. They are fairly small at the moment, 4 rounds. I don't know what to do about joining them together. I'm not sure I want to just join them as they are. I was thinking of outlining them all in the same colour to create a cohesiveness but am worried that whatever that colour is might dominate. I've seen some blankets that put four squares together and edge those. But then would I do all the same colour or use 2 or three colours. I've put pictures of the square on my profile, they are on my sofa, which is where the blanket will go.
Any advice?
