Design crisis!

I have worked so hard on this dress trying to figure out how to do it. I have to figure out how to make the skirt of this dress in hexagon motifs and thought I had it figured out but I just did some math and found that the circumference of the bottom of the skirt was going to be 56"!!!! That's for a 12 month size! So I don't think that's going to work. So, back to the hexagon shaped graph paper. I am determined to do this! The main problem is that I have to join these as I go so I really have to have it figured out before I start! But I have a bunch of dishes to was so will have to do this later.... I'll let you know when I've got it figured out!
