I'm working on a project that will be similar to this: http://media-cache-ec0.pinimg.com/originals/b7/ee/89/b7ee8922db675b9e0c6e24af80ffe006.jpg
I can't find that particular pattern, so I made my own and just made some granny hexagons. They are all different colors, I'm pretty much using all of my scrap to make different ones. My question is this: what do you suggest as the best way to join them? I was just going to crochet them together will a slip stitch, because you won't be able to see it from the one side so it won't matter what color yarn I use. But then I thought that might make them too heavy and I should sew them together. But then I thought I didn't know what color yarn to use because you will be able to see it and all of the colors are different. Any suggestions are welcome!
