Those 5 yo's made me crazy too. It wasn't until I was halfway through that I started wondering if the Hemlock Ring version would also work. Make two or three yo's and then drop all but one before doing the k1,p1's. Either way you end up with a bigger hole than a single yo would give. The Egeblad way gave me sort of lumpy hole edges that weren't such a problem on the Hemlock.
Are you finding the same thing?
