DIY Beautiful jewelry box | Craft idea with cardboard

detailed video 👉 https://youtu.be/-wbaeNyCkiI

The base of the box was made of thick (binding) cardboard 0.2 cm thick. See the video for all sizes.
I glued the parts with PVA carpentry glue, so it is more reliable.
The corners were sealed with craft paper.
PVA made a self-hardening mass from rice flour and wood glue. I added some liquid soap to it.
From this mass she blinded flowers and twigs.
I glued a cardboard form in the form of an openwork napkin to the lid. Here are the links:

I made half-beads for the walls using this mold:

I put spackling paste on the base of the box and immediately glued decorative elements onto the PVA glue.
Painted with acrylics in black, olive and tin.
