Occasionally, I try to make plushes that are a little more realistic, and resemble the natural form of the animal they are modeled after. One of the first I tried to do this with was the jellyfish. Formed mostly of spirals, long tendrils, and a half-sphere, jellyfish are a great place to start as a beginner.
As time progressed, I refined the design a little bit, and tried to use better materials. The proportions are also a little more accurate here. I'd love to have an ocean-themed relaxation room, and hang a few large jellies from the ceiling.
With a jellyfish, since there is a lot of variation in shape and color, you can have a bit of fun with the design as well. This one features a multicolor yarn I found and had to buy, which is rare for me. I normally try to stay away from multicolor yarns, but I think the colors really lent themselves well to the jellyfish. This variant also has an extra "stem" under the half-circle, and looks even more realistic, aside from the wild colors.
