I did this kit several years ago for myself. because I am a big Charles Wysocki fan. I have several of his kits by Dimensions Inc. They only come with the fabric stated. You can change to whatever size fabric you would like to purchase on your own. You will not have enough floss though, it takes more floss for a larger size project. I remember that I had enough for the 18ct. fabric, but there was not enough left over to have done a larger size. You can go to Cyberstitchers.com though to get a floss conversion chart for Dimensions Inc. floss to DMC so you would have enough for the project. I have copies of all the different kit conversion charts in my files. Hope this helps.
