Welcome to the Quilting Board!
I was going to post this site but thought I should check first to see if it was already posted. So here it is!
This site is huge!!! There is now 1311 sites.
I have two links on her site. Bonita is great and works really hard to keep the links current.
There is a ton and I do mean a ton of free info on her site.
You really should check it out if you haven't already.
This is a great place for a newbie to get started with areas for learning new techniques and lots of learning possibilities.
Here is the link to the Library section
This following link is straight to the Machine Piecing lessons. It is free to look at these. You don't have to sign up to use these. I have never signed up but I visit her site alot. Lots and lots of good info. It would take forever to read absolutely everything she has on here!
My Boston Block link is in the Machine Piecing Instructions and then click on Quick Piecing Methods and Tricks and then on Three Triangles - Quick Method
Then my site Bitsnpiecesworkshop is listed in the Bs and it goes to my Bookmark directions.
