I just had to do this this morning and it can be frustrating. I kept wondering to myself why this wasn't working as the directions stated only to discover after several hours of searching I figured it out on my own. The directions said nothing about a minor detail that made all the difference. The first part of the project will have to finish off the way I originally made it and from here on out I will do things the way I since discovered. Nothing like being brain dead! Hours of reworking the pattern.
I hear you with the frustration of having to rewrite someone else's instructions. Best of luck.
