The hard part is knowing who the designer is when you order from the catalog. Over the years, I have become familiar with the different designers "styles" and can narrow down who designed it and go to their websites. I have narrowed down which catalog is guilty of this and if I knew exactly which one it was, I would NEVER do business with them again. (If you know who, please send me a private Message.)
For those of you who have never ordered one of Sheila Landry's patterns, I urge you to do so. You not only receive a first rate pattern, she provides detailed instruction from beginning to end of how to do it. I have learned so much from her over the years.
For the beginner scroller, you can acheive great things with this kind of tutorial and should not be afraid to try advanced things with the right pattern.
