Here's how you can make a holster that will keep your snippers handy and yet be otherwise out of your way.
Step 1: Materials
empty bottle of dish soap in an appropriate shape
quick release buckle
long strap or thin scrap of fabric
spray paint that will adhere to plastic
Step 2: Cut the Bottle to Fit Your Snippers
Wearing the vapour mask and using the hot knife, refactor the bottle shape so it will accommodate your particular shears.
Cut away the top and bottom portions, then improvise a curved 'V' shape on one side to allow easy access for your hand.
While you have the hot knife warmed up, cut two slots on either side of the widest part to allow your belt strap to pass through.
Step 3: Spraypaint the Holster
Wearing the vapour mask, spray paint the bottle outdoors.
Allow to dry completely.
Step 4: Manufacture the Strap
Fold your strip of cloth in half right sides together so that it will be an appropriate width for your buckle.
Sew it down longways.
Turn it inside out.
Top stitch it along both lengths
Step 5: Attach the Buckle
One side of the buckle has a permanent connection to the strap. Thread the strap through this side and sew it on as indicated.
Step 6: Thread the Strap Through the Bottle
Now that the strap is ready, possibly the paint is dry on the bottle.
Thread the strap through the two slots you made earlier.
Step 7: Affix the Adjustable End of the Buckle
Thread the adjustable end of the buckle onto the strap as shown.
Step 8: Resist This Impulse
Step 9: Now You Are Prepared Any Thorny Encounter
Step 10: What Didn't Work
My first design included two straps which were going to attach to the belt, but I found that the holster swung around too much and required two hands to get the snippers out.
