The pattern is for a 18.5" x 18.5" block. The pattern has lots of sections and lots of small pieces but there are no complicated seams (such as y-seams). Paper piecing instructions are not included but there are many great tutorials that are available online. Each section is clearly labeled and a 1/4" seam allowance has been added to each section. All you need to do is print it out and get started! I advise setting your printer to "Actual size". You may sell items made from this pattern on a small scale but please include "Pattern by Sewing With Squeak" in the description.
