thanks, I have a bunch of grandkids(10) and they all seemed to want lego's. Now that they are older ehhh.... not so much. So I use what I have AND it work good on weird shaped like this curved arm rest to save on molding rubber(that stuff is expensive.) over $150 a gallon for the good stuff so I try to save material where I can. ohh and they are reusable for different shapes.. win-win for me!
