Good news, I found some more of these very popular cardboard kitsets.
Still a few available.
The rectangular box size: 10¼" long x 6¼" wide x 3" high. (26cm x 16cm x 7cm). A great size for storing treasures.
Click on the zoom image button to your left and you will see the box open.
Cover your box with your own choice of fabric. I used the
flower sugar yellow on the lid and inside fabric and the
flower sugar dots as the outside of the box base.
I needed just .35m for the outside fabric and .35m for the lining.
You can decorate the box with lace, ric rac, tassels and beading or even crazy piece the lid and add images printed either with TAP or inkjet fabric sheets.
I found these photos of similar boxes decorated with lace and memorabilia. These photos may give you some ideas for decorating your own box.

Make the box as individual as you are!
This type of creativity is wonderful to get a young daughter or granddaughter interested in crafts, fabric and maybe quilting!
