This question was posted the other day and I thought it may be something that others were interested in:
I am starting Recorder Karate for the first time and looking for an idea pertaining to the belts that is more cost effective. I see you have yarn. Can you explain how you utilize the yarn as belts and what holds it into place?
I hear you on cost effectiveness. My school started out at just under 600 total population and now we are at around 900. I have always used yarn for belts and honestly, I have not had to buy new yarn in the 6 years I have been doing recorder karate. When I first purchased the yarn, I stocked up (2 packages per color).
Since I only use this with my 4/5 graders, it takes a while to go through. If you want to go the yarn route, I would buy the larger packages of yarn. JoAnn's/Michaels/Hobby Lobby coupons are great. I took several trips in order to get all the yarn I needed. You can also ask parents for donations. Since this isn't one of the more expensive items, I have had parents donate a package here or there.
My kids are in charge of cutting the belts but I have to be specific about the process. When we first start RK in 4th grade, I teach them all how to cut them to the right length. I use a bucket in my RK box as a measuring tool. Otherwise, you'll have to listen to "my belts too short"! :) Another way of doing this is by cutting the yarn ahead of time but I don't have the patience to sit and do that, so having the kids cut the belts works for me.
Do you have any questions about recorder karate? I'm happy to share how I have made this work at my school.
