So it took me a bit longer than the 1-3 hours estimated on the pattern, but it's finally done.
I'll be putting a ribbon through the top of the acorn for ease of carrying, but I think it turned out alright. Not sure I will be making tons of these (at least not with a 3mm hook), but I really enjoyed the project.
I hope my swap partner does too!!
It feels good to make a cute, simple project. I recommend this pattern for folk who are crochet/amigurumi savvy.
