Hello Becky!
I also make my slings about the same way you do!
Except for a few things:
1. I use one color...hehe...gonna switch to a few (maybe camoflage)
2. I make my loop like any loop and its not braided together...allthough it looks nicer that way.
3. I also use 6 strings to make the Sling Stronger and since i only know how to braid a 3 string braid i melt the ends together to form 3 thicker strings.
4. When I reach about the middle of my string i dont cut it but instead i punch some holes around the pouch and "weave" the 3 strings through. 2 for the edges and 1 down the middle.... (hmmm i really need to get some pics...)
Then when the weaving through the pouch is done i finish of the braiding and tie a knot at the end...
Basically A nice Apache style Sling!!!!!
Very nice Sling!!!!!!!!!!!!!!!!!
