Leslie -- While I was taught to press seams closed always, I have, over the years, sometimes chosen to press open -- if it works better. I have no dog in that fight. I'm also very wishy-washy about always prewashing (tongue twister, anyone?)
But when I buy a pattern (which is very rare) or a book or mag, I really, really do expect the author to give very clear, concise, efficient directions and yardage requirements. A big part of why I don't buy patterns and books is that this expectation is not always met. It's also why I won't do mystery quilts and am leery about quilt-alongs (unless they give full info from the get go). However, there is obviously a market for them, and people who like working that way, so good for them. And I hope that in their travels through the world of quilting, they learn some very useful tips and tricks and techniques that will help them through the frustrating parts -- which, I would like to think-- this thread has actually done for at least one person.
