Non slip chair pads

Back at Thanksgiving we bought a beautiful new dinner table and chairs.  But like most chairs they were in need of chair pads.  We found some at walmart that we liked. The only issue was that the ties were so tight on the back of the chairs and most of them broke :(

When we were visiting my husbands paretns over Christmas I noticed that my mother in law has chair pads with a non slip bottom and no ties.  I thought it was the perfect idea for fixing mine. 

Now that school is over I have finally found time to sit down and work on them. I had some non slip material on hand already.
