I had bought some old roof slates years ago and knew I wanted to make a house sign with them but couldn't figure out what to do.  Then I got a D1 Pro 5W for my birthday and the idea finally came together!  With the 5w, I had to use the Stone Coaster as the material to get a base setting.  I sprayed the slate with a satin finish before and after.  Used Inkspace to design then imported to XCS for fine tuning.  Really happy with the results!
