Step 5: Make Paper Joiners.

Cut a rectangle of newspaper about 10cm x 20cm and fold it in half lengthways so it's now 5 x 20.
Roll it up tightly so that it's about the same diameter as the inside of the tubing and tape it so it doesn't unroll.
Crochet and maths is the most natural combination of crafts I've ever seen. :)
Great Instructable! Yarn AND math. The right side of my brain is feuding with the left side and creativity is winning! Yea! Oh, and it is Duck tape (it says so on the inside of the tape) not Duct tape. Ha ha ha!
Ah Nuts! I've gone all addlepated from a' staring at the picture...
These are <em>so cool</em>!<br/>I love your beautifully clear explanations. (Didn't know the interior was a Reuleaux triangle, either.)<br/><br/>Fantastic!<br/>
i can't wait to make one of these for the 2yo great niece. and my father in law the retired math teacher is gonna love it! thanks maplesyrup! this is "sweet"!
ha maplesyrup = sweet xd<br/>
This is great, and very well explained. Math &amp; craft, just like babair sez, they're an unbeatable combination.<br/><br/>(I have to admit, on first glance of the title only, i was half-expecting some Lord of the Rings thing, but now I know that &quot;Borromean&quot; != &quot;Boromir&quot;.)<br/>
I love it when math and craft come together! :-)
would be a great baby gift
its best to start them early in puzzles and math : )
wow, this is pretty sweet, i could imagine this being a nice bracelet, or if you flattened it a little, a coaster. +1
what do you use borromean rings for.
ahh lol i see now, i read the text lol. its a mathematical failure of sort, like them hovercrafts made of aluminum and old CRT screens.
Wow! This is really Cool! Great Instructable!!!!
