I have made some more Babette squares though! It's fun to mix and match the different colors and see how they come together in the squares. There is a Babette group on Ravelry (they also do hexagon blankets, which is really the reason I started messing around with crochet) and it was mentioned that the smaller squares all seem to run a bit bigger than they should (compared to the other sizes) and mine seem to be doing this too. (If you look at the medium red square on the right, the two tiny squares underneath it should be the same size as the lower edge of that medium square. As you can see, they're a little bit bigger.) I'm going to try using the sliding loop* as a center instead of the start given in the pattern because once I've gotten my first round worked, I can tighten up the loop and make the center as small as possible, which might solve the slight size issue with the smallest blocks. If this works, I'll just do my smallest squares this way from here on. I will probably still use the first ones I've made because there are so few - I'll just space them around the blanket and make sure I sew them in carefully.
*I learned the sliding loop technique as a start for the star motifs I made into a scarf last Fall from the book Beyond the Square. I Googled for a link to this technique and while I found something similar, it wasn't going to hold as well as the one in the book (so I'm not linking it here.)
