|An easy way to discover which patterns are going to be discontinued is too look in the pattern drawer. The little dividers which have the pattern numbers have another side to them, in a different color. For instance, if you open a Vogue drawer and some of the dividers are PINK....those patterns will not be in the next book.
When patterns are 99cents, I often pull up a chair to the drawer (when it's not super busy at the store OF COURSE!) and just look to see which patterns are going to be discontinued. Every so often a pattern I consider to be a forever classic is going to be discarded and I may buy one in every size, expecially if I have made it before and been pleased with it.
