Egyptian gloves

This time an unusual puzzle, I'm calling it a "covering puzzle". Why? Because the goal is to cover a geometrical structure with fabric.
Let me introduce you the Egyptian gloves designed and made by Jon Leaman. It was his entrant for 2017 IPP competition contest.

You're provided with 3 different challenges. For the 1st one you need to cover the pyramid with a squared bag. Normally you should not have a lot of difficulties to do so, especially if you've ever played with Iwahiro's puzzles. I managed to solved it. The dimensions are very precise, so no need to use any force at all.
For the 2nd challenge (see picture above), you're provided with a band of fabric and I managed to solve this challenge as well. However, my solution was different than the official solution :-)
For the last challenge, you're provided with 4 triangle pieces, I'm still strugling with this challenge.

I am very pleased to see new kind of puzzles. In my opinion, this is a real novelty and it changes from the "usual" puzzles. Plus, here you have not only one, but three puzzles!

I really like this puzzle: it's original and fun and also challenging. I do hope that Jon will come up with new challenges with the same pyramid or with other shapes.

If you're interested, Jon has an etsy page where he sells his creations and the price is very reasonable.
Enjoy!
