It's quite an elaborate software program that allows you to create your own quilt designs and/or use their built-in block patterns to create quilts. There is a *lot* you can do with it, but it comes with a pretty steep learning curve. Some people take to immediately; others never get the hang of it. Cost usually runs $150 to $190 depending on whether you can find it on sale or not. Whether it is worth it to you depends on whether or not you actually learn how to use it. Some people do; some don't.
