Thank you for posting this! I appreciate the resources :DDD
It’s proving to be quite a challenge, since I am a mere confident beginner and the instructions are fairly summarized. If it’s any help to anybody, I recommend watching this video I found as a guide, as a lot of the assembling can be applied to this project https://www.youtube.com/watch?v=ZghLltCIJmo
Also, it is indeed oversized, so stick to your size- or maybe even go down a size unless you’re looking for really loose fit.
Thanks again!
