Since I started my 99 Post Stitches project, I wanted to make the squares into two afghans. For the first I collected together all the lighter-weight squares, and the heavier, thicker squares will go into the second afghan.
First I joined the squares into rows, and joined them with slip stitch. I picked a few colors and used those to attach all the squares touching those colors, then did the same for all the remaining colors. I slip stitched the rows together with white yarn, and tried to make the corners of each square line up. Once that was done, I finished the afghan off with a row of white single crochet around the outside for a simple edging.
The front looks very clean, as I only used the back loops for the joins.
I like the white lines on the back, and wonder if I should use white for all the joins on my next afghan, instead of matching colors.
