DIY Groovy/Pattern Quilting Boards
 

Hello,
I have been researching how to make Groovy or Pattern Boards that are used with a stylus and have read most of the older posts, but was hoping for more recent posts from people who have/are making these boards and hopefully willing to give details. What material is best to make boards, etc? Can the grooves be made smooth and not jerky? What are you using as a stylus? depth and width of the grooves for design?
Thank You!
