Step 1: Tools & Supplies

The tools & supplies needed for this project are pretty simple. You will need some 1″ webbing, a pair of scissors, a measuring tape, a D-ring, three sliders and a sewing machine.

If you can’t find the sliders, metal O-rings or D-rings will do just fine. But you will need a plastic slidelock for the adjustable part of the collar.

Some sources that I use for hardware & supplies are

cdwplus & strapworks

However, most local fabric stores will carry all the supplies that you need.

Step 2: Sewing on the First Slider

First, we are going to make the main part of the collar. For this tutorial I made a medium sized collar, so I cut a 20 inch piece of webbing. Fold the webbing over one loop of the slider and sew two seams so that the finished product looks like the second picture.

Step 3: Making the Control Loop Part 1

Cut a 12 inch length of webbing and thread on the remaining sliders. To add the D-ring, overlap the webbing ends by about two inches & pin them as demonstrated in the picture.

Step 4: Making the Control Loop - Part 2

Sew 2 seams each on either side of the D-ring co that the finished product looks like the second picture.

Step 5: Putting the Collar Together

Taking the end of the main webbing of the collar, thread the it through the one of the sliders of the control loop, taking care to make sure that the D-ring is facing to the outside. Now thread the webbing through the slider of the collar.

Finally, thread the collar webbing through the last control loop slider as demonstrated in the second picture.
