I am in this year. I have watched previous years and always kicked myself for not trying one of her patterns. I decided to do a Christmas theme, so my colors are red, green, gold with a gingerbread brown "constant" and cream background. I hope this works well. So far I have my step one cut and halfway sewn. Just need time to finish the twosies. I was glad to see an easy step to start the process.
Someone commented on the estimated yardage - if I remember correctly, the estimate had a quarter yard "fudge factor" per color. This will be a big quilt, so the yardage seemed about right, especially if she uses any quick corners because those eat up yardage. Also consider what is in the seam allowances. The smaller the pieces, more ends up on the back. Ie 1/2" finished strip will have as much showing on the front as is in the seam allowance.
