Designing a felt lunch bag is in progress… in spite of having such a long break :). The last time, I was searching for the best way to make the bag waterproof, testing 3 kinds of coating materials: waterproofing splay, splay varnish and acrylic medium.

As a result, the acrylic medium worked very well but the surface of the felt has become so hard like sandpaper. So I wanted to see how the lunch bag with acrylic medium applied on felt feels, by making another prototype and to see how making process goes also.

I applied 2 thin layers of acrylic medium at intervals by a painting knife about a third of the side parts from the bottom and the bottom part of the lunch bag then sewed them together.

There was no technical problem during the working process, but I thought the surface of the felt became really hard. It's not pleasant to touch. It feels so artificial and disappointing. Applying something on wool felt to make it waterproof loosing its good nature seems somehow wrong. That was the point where I landed through having done all the examinations.

However, I have still the last alternative: buying laminated fabric or oil cloth for making an inner bag. The good nature of the wool felt is retained on one hand, and the removable, waterproof inner bag is machine washable on the other hand. Let's go forward with this way.
