They turned out so cute that I decided to see what else I could crochet to put in a jar. I found a octopus pattern by Sarah Hearn. I used a thinner yarn and smaller hook to make it fit into the jar.
W decided that the octopus was his favorite. I currently have four colors of those.
I hope to get them on Etsy soon. For now I have the information about them on my Facebook page. A big thank you to wolfek for reminding me about this project idea.
