Thank you all for your comments! I have decided to go with the lambswool. I really liked the Maple Sugar, but it had a little bit of a pink tone that I just didn't like with the thread colors. I have also decided to only do the first six of the designs. I enlarged the top and bottom of the chart from the Lizzie Kate website and taped it together and then made another copy.
This will be good for me because I always start good on these banner projects and then fizzle out towards the end, so hopefully with only six I'll get it finished and maybe by Christmas! :)
