More Shock Cord Mount Ideas Part 2

While Jason Wentworth (Blackshire) used standard copy paper, I wanted to try some Tyvek.
This is used in strong envelopes, you can't tear through it every easily.
THE TYVEK DID NOT WORK!

I had an extra Express Mail envelope I never used. The entire big envelope is made of Tyvek.
It does say on the envelope: "This packaging is the property of the U.S. Postal Service and is provided solely for use in sending Express Mail. Misuse may be a violation of federal law."
I wouldn't call it misuse, but instead - research!

When cut into a shock cord mount, it reminds me a little of the old Centuri self adhesive mounts. Sure, this is white, the Centuri mounts were a flame resistant silver. But it has reinforcement fibers running throughout the paper.

The Tyvek feels a little slippery, it'll be interesting to run a few tests to see it it can be glued in securely.
Elastic shock cord was woven through the holes.
The side without the holes got a coating of glue and was folded over onto the corded side. After drying, I glued the finished Tyvek mount into some scrap BT-50 and let it dry overnight.

In the morning I pulled on the shock cord. It pulled out of the Tyvek!
The Tyvek was too slippery and probably resisted being permiated by the white glue. Without much trouble, the entire mount was pulled out with tweezers.

Lesson learned:
DON'T USE TYVEK FOR A SHOCK CORD MOUNT!
This style mount will work fine using paper or cardstock.
