I made a survival collar for Snickers. The picture below is a survival bracelet; they are becoming very popular. You can unravel them and have 8 feet of strong rope (parachute cord or paracord) to use for whatever. A corgi collar will give you 12 -15 feet of rope and only cost a few dollars and an hour to make. I used the tutorial by Knot the Ordinary on Instructables.com. My feminine version is made by adding pony beads and by tugging on the knots every two inches to spread the knots out. (tie 6 knots tightly then pull them away from one another, tie another group, then pull them apart, etc.) It is hard to explain unless you have the piece in your hand, then it is very simple.  When you finish the collar you tuck the ends under the knots; if you have spread the knots out, leave more tail to tuck because the knots are not as close together.  Don't use the metallic pony beads, the finish wears off in just a few weeks. I recycled old collars for the hardware, or you can buy buckles at the craft store. D rings are sold at the hardware store. I only used a split ring for tags because I don't attach a leash to her flat collar. If you use a D ring, slide it on between the buckles before you start tying knots. After you make a one color collar, try the two color, I used the tutorial by Paravival on Instructables.com. I bought my cord (16 ft.) and pony beads at Hobby Lobby. I also saw cord in more colors and larger packages at Home Depot. My next project is a leash!
