a skater friend gave me 8 sheets of the 4 x 4 1/2 sheets. I can cover my left forearm with two of these instead of six of the 3 x 3 1/4 sheets. That was a nasty crash. worst part is my knuckles. ground them down several layers deep, and they don't make knuckle bandages.
didn't keep me off mandeville canyon yesterday though.
I found 2 sizes of tegaderm (larger than the 4x4 3/4 found anywhere) at my local CVS in oceanside. I think the largest with a pad is 6x8". The other is like 5x7". Not even the medical supply houses near my house stocked it. I was quite surprised!
