Finishing techniques

I made some dish cloths that I want to combine to make a little afghan. What’s the best way for me to do this? Any suggestions on good for finishing techniques?

thank you,

I think the best way to seam them together would be the edge-to-edge seam. It will lie flat and not leave ridges. Scroll down on this page:
