There's a reason for all this interest in yoyos. My guild is playing "The Great Yoyo Race." It's a game that I wrote about yesterday. You can see the game rules here.
You can find these and about 40 other pins showing cute, fun ways to use yoyos on my Pinterest board, "yoyo, projects."
If you would like to join in with me and make some yoyos, let me know in the comments. You can make as many as you'd like: any size, any color, any shape. Use a yoyo maker or make them the
old fashioned traditional way. It's all up to you. We'll just get together during the first week of each month to report on our progress. You write a post and throw in a few pictures of your yoyos and then come here to add your link to the group.
The more people we have playing, the more fun we'll all have visiting and looking at what everyone else is doing.
Finally, if someone really wants to get in on the fun and is willing to be a yoyo partner, please email me so we can chat and plan. (firstname.lastname@example.org)
