This haberdashery or notions store, 
is filled with ribbons, buttons, needlework patterns and materials, 
threads, and all manner of things.

This is a drawer filled with colorful cards.  
I was remiss in not knowing for sure how they are used, 
but I guessed that they were for wrapping embroidery threads 
of several colors for a single project.  

What I really wonder is 
WHY did I not buy a few to bring home?
