I’ve used 5 skeins from the 2019 Skein Queen Advent Calendar -- all shades of green called Fir Tree.

This is a quick and enjoyable knit, although it did take a couple of tries to get the spike motif down. I would have found a visual, (photo or video), helpful, but it’s not imperative.

I used the bind off from the pattern, however I find it a bit too loose for my knitting style so will probably go back and do a regular bind off. As a loose knitter I find that usually works okay for me.
