Made about 60 & have at least 30. Some are very worn out & my furgrandbabies use them. When they get really bad, my husband takes them out to his garage to cover his car. It took me years to make any improvements in my "techniques?"--it took finding this board & all of the tips, etc, I found here :) :) :) I was a beginner for YEARS- now I am an advanced beginner----THANKS ALL!!!
