That's a nice straight forward pattern. As I was whining earlier it's always the border that holds me up. Changing colors at the end of rows is always good because then you don't need any knots.
The only thing I don't like about your pattern is that I avoid starting rows with a dc. I don't like the whole it makes. I'm a big fan of the half double crochet (and popcorns
The blanket I just finished was fun (still no border). It started with 2 stitches and increased into a big triangle and then I did the opposite and decreased until the triangle got smaller and smaller and I ended the blanket with 2 stitches too!
Does that make any sense at all?? It was great that the rows got shorter it gave the feeling I was finishing fast.
Good luck Merme! I sure hope you post a picture!
