Patterns are your blueprint. If the blueprint sucks, your house will suck. Sending back the samples after a fitting for the pattern to be adjusted costs money every time, but it's money well spent. I told myself it would take at least 6 rounds of revisions per style so that I wouldn't go crazy with impatience. The process is tedious and time consuming and frustrating, and between rounds 3 and 4 I started to loose my cool even though I had mentally prepared for more. Luckily 4 of my styles were completed in 4 rounds and the remaining 2 styles only needed the 5th adjustment so I finished 1 under my preparation.
