After looking around for just the right knobs for my vintage trailer I decided to create some samples in case others would like to buy some. I took five ceramic knobs and hand painted them with lead free glazes. Each one measures 1.75 in in diameter and about 3/4 inch tall. These are just samples of what I can do. You can see more photos at this web site on Etsy where I sell them
I can do any color combo's and open to other designs. These are free form hand painted so designs are not cutter cutter same. Happy to work with your decor theme and custom colors though!
