2.0's Explained Blog
What is a 2.0 or 2.1?
A 2.0 is a new pattern. Just like a new edition of a textbook, a 2.0 (or a 2.1) version of a pattern features the newest content and best techniques we have to offer. Updates may include improvements in the instructions, layout, illustrations, and/or changes to the finished project itself in order to make it more functional or easier to make. The 2.0 versions may also include Add-on Videos to ensure your success.
A 2.0 is not a correction. We are improving the pattern. Every 2.0 goes through the same process as an entirely new pattern.
Although we recommend that you upgrade to the 2.0, we know that you will be able to make something you will be proud of using the original pattern. We know we have!
