I love the idea of the mat/sit pad idea, and I must say that yours is much more advanced than mine. I just use a peice of wal-mart blue cc foam for my pad. I am definantely making your version tonight!
I know alot of people use the end caps you are talking about. Could you PM me with plans to make them or a place where I can get plans/ buy the end caps. Thanks sorry to hijack. I digress.
"Fearless warriors in a picket fence, reckless abandon wrapped in common sense
Deep water faith in the shallow end and we are caught in the middle
With eyes wide open to the differences, the God we want and the God who is
But will we trade our dreams for His or are we caught in the middle" - Casting Crowns
