In other words: when choosing a block size in EQ7, do I need to add seam allowance? No. EQ7 will do that for you.
When you tell EQ7 what size block you want, anywhere in the program, you type in the FINISHED size. EQ will add seam allowances when it presents the pattern.
When a magazine or EQ gives the size to cut a strip for rotary cutting, that INCLUDES the seam allowance. In this instance, you’re not talking finished size but rather construction sizing before seaming. It’s always good to check, though, in a magazine or book pattern, whether the templates include the seam allowance. Often it is obvious that the template includes the seam allowance because it’s drawn that way, with a dotted line to indicate the addition of the seam allowance.
