I don't follow the "rules" of crochet very well. Sometimes I knot, instead of just tie down. I like to use a heavy worsted yarn, with a medium worsted yarn - for texture. Particularly if I'm designing an image into the blanket. I don't care if your "suppose" to use all the same "kind" of yarn, in a single project. Poppycock! Don't interrupt my art - with your domineering and misguided "rules". I write up the Care Card to the most delicate yarn in the project!

But for this project, I did follow the rules and used the same yarn throughout the project. I loved how it turned out. I used a slip stitch to connect the squares and strips, as a whip stitch always has a greater danger of coming undone. This resulted in one very textured side that babies will love to touch; and a soft, smooth side to keep baby all comfy and warm. A whip stitch would have given both sides a flat, smooth finish - but be less sturdy to stand up to the toddler years of tent making, cape wearing, and make believe.
The leaf border finishes up the blanket with a slight ruffle, and just the right touch.
So, the fun part is over. Now on to the tedious part.... blocking it, and truly giving it that finished touch! Ugghhhh....
