This is a “Twin Loop” sling I made for throwing tennis balls. I am sure the idea can be resized for any other round object.

This Twin Loop sling performs very well and is very, very quick and easy to make. Please see this discussion about the performance of the Twin Loop sling as well as ideas for different variations of this Twin Loop sling:

Here is a pic of the Twin Loop sling and the tutorial for making this sling is below.

Step 2:  tape the center of the loops together.

I used masking tape. But perhaps duct tape would be better (see next step)

Step 3: permanently connect the center of the paracord loops and the pouch will be finished.

IMPORTANT: the centers of the paracord loops should permanently fixed together over a distance between 2.25” to 2.50”.  This distance forms the pouch to tennis ball size…so adjust this distance if you are using some other size ball.


Option A: since this sling is for tennis balls, very likely just duct tape would do the job of keeping the paracord loops connected. Just make sure you use enough layers of duct tape so that the loops do not fly apart as you spin the sling.  This is the easy, fast option.

Option B: using #18 nylon mason line, connect the centers of the paracord loops with whipping. This is the option I chose and it did not take too much time to do. Perhaps it is more durable than duct tape as well (?)

In any case, I did not have duct tape on hand but I have plenty of mason line, so option B was for me!

That ended up looking really good.  Nice job!

I wasn't a fan of the masking tape.  With tennis balls, probably not too much of a problem.  But my concern with anything heavier is it would give out at some point without warning.  Duct tape I think would be much better.  I think you would see it wearing out and could replace it before a total failure.  Gorilla tape would likely do the job well too.

But the cordage wrap, that looks great.

Heres what i came up with.
I took each loop and twisted it 180° so it creates a figure eight. attaching the two figure eight heads together like the twin loop and then compressing the figure eight so where the two cords cross is turned into another double strand warp for the weave. I took the black cord and wove that between the two stranded red warp, the red and yellow warp, and then the yellow-yellow. The two loose ends on either side were then joined with a brummel lock and tapered from two strands @full thickness to 1 gutted cord on the release and to a full cord on the retention.

Try not sending the original photo, but only a screenshot from the screen, it will be just the right size.
