Bernat yarn website here. Of course now my daughter wants me to make one for her too. :)
The pattern calls for Bernat Handicrafter Cotton. I used Caron One Pound in Off White and Red Heart Super Saver yarns in Chocolate and Spring Green just because that's what I had here in my stash already.
I pretty much followed the pattern, but for the doll part I skipped the joining step at the end of each round and just crocheted a huge spiral, marking the beginning of each round with a safety pin. Yes, you can buy those split-ring stitch markers, but a safety pin or a piece of scrap yarn works just as well and costs quite a bit less. The pattern didn't specify when to put the head on, so I decided to do that last to make it easier to get the dress on the doll's body. I also made the dress all one color instead of doing the ruffle in a variegated yarn. I think I may do the ruffle in a coordinating variegated yarn the next time I make this.
