I solved my crochet problem all by myself!
None of the squares are blocked yet of course, but using the sliding loop which allows me to tighten up the center of the square makes it just the right size to fit to the medium square. I can't take responsibility for the technique of the sliding loop - I learned that in Beyond the Square - but since I learned the technique for my little star flower motifs that I made last Fall, I realized that it might be just what I needed to make the tiniest blocks for The Babette (I think it needs a "The" in front, don't you?) the perfect size. If you look, you can see that the tiny blocks on the right don't have a center hole, while the rest of the blocks do (and will, as I continue to make them). I don't think this is noticeable and I certainly don't want to downsize the rest of the blocks. Do you guys think it's noticeable?
Have a great weekend and stay warm!
