Thank you all for your replies.

RLM--I am not going to use the piece to hold bobbins. I just wanted
an understanding of how to determine the width of the slit and still
have it grip. As it turns out, a piece of garden hose will be too
large.

Bob Engelhardt--Thank you for the detailed explanation. This will
help me figure out what I need.

JR North--I tried to search for such an item.. Do you happen to know
more about it or what it's called?

Ken Sterling--I haven't tried Lowe's, but I have tried my local Home
Depot. They don't have the tubing I need.

Martin H. Eastburn--I will make test cuts to experiment. For now, I
have a limited amount of tubing, so I thought if I could narrow down
the number of test cuts to do, it will help.

Again, thank you for your responses. I appreciate your efforts.

Regards,

Amy
