Additional Notes

This PDF pattern includes all pattern pieces and step-by-step instructions with illustrations.

It's not that the sizing isn't accurate (it's fine!), it's just limited by the triangular structure of the pattern. It is possible to do a full bust adjustment, but it's a bit more complicated than would typically be the case. I didn't try that, so no comment on how difficult it would be.

I am totally in love with the pocket design and the overall cleverness of this raglan.

Although I love the design/asthetic of this pattern, I gave it a low mark overall because the neckband was improperly drafted. The knit neckband was not shortened, which results in a gaping neckline. I was able to unpick and fix it, however this is such a fundamental and obvious flaw that I am disappointed that it has not been corrected.

This pattern is super cool but it was a bit tricky to do as a beginner and get a tidy result. I will try this one again now that my skills have improved! This pattern is nice and versatile too as it includes both a cropped and a full length option to choose from.

I can't say enough good things about this pattern. Very well written. Large size range. FBA instructions included for those who need them. Multiple style variations as well. Loved it!

Nice pattern that went together easier than I expected (still a little tricky to do the triangles, but certainly not impossible). I skipped the bust adjustment, but if I made this again I would not skip it!

I plan to make more - there are variations that I haven't tried yet.

I love my sweatshirt! The instructions are very thorough. I highly recommend.
