So true, Eileen!
If possible, a pattern should be tested by several very different quilters to see if it works. What's clear to one quilter may be totally incomprehensible for another.
And the perfect situation for me would be if the pattern designer would come and visit me, so that I could watch him/her making the quilt, taking notes for myself. I'd then like a weekend straight after with nothing else to do, so that I could make the quilt whilst all the instructions are still fresh in my mind.
If I wait 6 months, even my own notes sometimes don't make sense anymore.
