Silk thread

While looking for some sewing thread I thought these would be suitable for the TinyTuesday challenge.   Unlike the usual polyester used now they are all made of silk and belonged to my grandparents with their tailoring business.  In the extras I have included a photo of the thread wound round their cardboard reels. The thicker thread is suitable for buttonholes, button sewing, quilting, smocking, faggoting and fancy stitching.  (Faggoting is joining two pieces of fabric together with open stitches in a crisscross or ladder pattern. Before elastic thread was commonly used, smocking was used to gather fabric using embroidery so it could stretch)  
The thread is actually very thin and almost impossible to see that it is made of several strands.  I haven’t been able to find out much about Perivale Pure Silk but think they are all at least 70 years old.
