There is a book by Sara Nephew called building block quilts and is has several geometric designs in it. hope this was a help for you
I really think a digitizer needs to tackle this one 4 u dear especially if U cannot get what U want from emblibrary
You could have posted this in the Q & A section whith your prior post and will probably get more help. I anwered your question there and as Shirlene also suggested emblibrary.
Oh - my - maybe one of the digitizers will tackle this - I haven't seen one - on any of the sights - but you could request it on Emblibrary - they might do it for you. Good luck, dear!
