jewelry case

I was asked to make jewelry case for silver seashell necklace.  My friend is an activist who preserve sea lives.  Jewelry case from scrap fabric seems to be appropriate for her jewelry.  I made 2 prototypes for her both have bright blue in its combinations. For the triangular, she can stitch out of any materials  that is available even paper.  For this prototype I use blue vinyl.   Hope she likes them.
