In my youth (...ahem) I sewed a lot, mastered Vogue Designer patterns and used all kinds of fabrics. Daughter Sarah is now following in my footsteps and I am so happy that she is having fun making her own clothes.

In the fall garden there are spider webs that use the zig-zag stitch to sew across the circular filaments of their web - it is very distinctive with the yellow garden spider. The purpose of the zig zag is unclear; here is a comment from wikipedia:

The web of the yellow garden spider is distinctive: a circular shape up to 2 feet in diameter, with a dense zigzag of silk, known as a stabilimentum, in the center. The purpose of the stabilimentum is disputed. It is possible that it acts as camouflage for the spider lurking in the web's center, but it may also attract insect prey, or even warn birds of the presence of the otherwise difficult-to-see web. Only those spiders that are active during the day construct stabilimenta in their webs.
