I have been playing around with the soda-washed Bed, Bath and Beyond cooking twine as the bottom strings for 100" top-string loops whose top strings are usually full-ply rayon mop yarn or webfoot microfiber mop yarn (both from RubberMaid). I have been impressed by the size potential with a strand of this twine. I have been able to make bubbles (closed ones) that rival the biggest I have made. I have made bigger bubbles with a single oversized strand of rayon (which seems to hold a bit more juice than the twine and is more self-closing at this size when empty), a double-strand rayon bottom and t-shirt yarn bottom. I have been thinking that I would like to try both a double-strand of twine and a twine/bamboo yarn combination to see if it would improve the size potential.
I could create some twisted cord easily enough, but since I already have a couple of twine bottoms and a bamboo string bottom, I thought: "why don't I see if you can use two modular bottoms together without twisting a new cord." If it worked, I could try them out and make a twisted cord of whichever combination seemed best.
I figured it was worth a try though I was doubtful that it would work -- otherwise (I thought) lots of people would have already done it. However, I tried it and it worked.
I decide to go with the twine/bamboo combination since I thought that two strands of twine migh be overkill. I have been finding lately that I have better success with a single rayon strand as a bottom when trying to close monsters than when using a double-twisted strand.
It is important that both bottom strands are precisely the same length. After clipping the bottoms onto the clips, I noticed that one was about 10 inches longer than the other. So, I used a lark's head knot (which is easy to undo) to put a split ring on the too-long strand at precisely the right point and clipped the excess to the leader to keep it out of the way.
The BBB twine and single bamboo strand made a very effective combination.
The next experiment is to try multiple tops to study the influence of the top on the size potential. And, I still want to see how two strands of twine work.
