I have this one.
https://www.etsy.com/no-en/listing/5...on-3002-sewing I use to pin my tops and backs to the leaders on my rack for longarming. I only wear it while actually using it, which is when I am either pinning or unpinning a quilt to the rack. Then I remove it. I love mine. It is very similar to what you described as the stuffed pumpkin but mine the bands are velcro at the ends, no elastic and the cushion itself isn't super large like the stuffed pumpkin ones I found on Amazon. I really can't imagine leaving it on my wrist while doing any tasks other than pinning. It tends to catch on things, especially with a bunch of pins sticking out of it like a hedgehog!
