Sharon suggested I contact Barbara Brackman for her views on the pattern. Here is Barbara's reply to my email.
Wow. Never saw them before. See this posthttp://barbarabrackman.blogspot.com/2010/02/mystery-pattern-swirl.html
I'll put a link to your post in my next post on mystery patterns. How's that sound?
Thanks Barbara for some further insight to these stars.
**and another update**
See Barbara Brackman's recent post for an update.
You may have realised, if you've read a few of my posts, that I have a penchant for the somewhat unusual, quirky, ideosyncratic, eccentric (OK you get the picture).
My guess is they are 1920's-30's vintage. The blocks are all hand pieced, and someone has started to set the stars together with a plain muslin... I'm thinking that I'll continue this, although I will need to de-construct and re-piece some of the stars -the points are not quite matching up. Fortunately I consider hand piecing and set-in seams enjoyment.
Percy will have to wait, though, others are clamouring for attention. sigh.
