Zipping jackets

 Had to figure this out myself since the left hand has almost zero pinch grip to hold the side of the zipper long enough and strong enough until the zipper has been fully engaged.  Had a loop of cord/fabric sewn onto the fabric next to the zipper pin, where I use my right hand to insert my left thumb into the loop. Since there is enough spasticity in my thumb it doesn't straighten out and is strong enough to get the zipper started. My OT's should have recommended this. Much faster and more portable than my other solution; a Vise-Grip.

The loop, it probably should have been a half inch longer for ease of insertion

It takes a bit of effort to get the thumb out of the way to get the zipper pin inserted into the zipper tab. Damn spasticity.
