Bonnie suggests these rulers, but they are by no means required to do her quilts. She will tell you to use whatever method you want to use, as long as you end up with the necessary size units. Her quilts are time consuming in that they have many pieces, but they are quite doable. There is a large and active Yahoo group devoted to chatting about all things Quiltville. You might consider joining, as there will be many folks who will share their hints for success as the mystery unfolds. It is called Quiltville chat and you can find it by going to Yahoo groups. You do need to request permission to join.
As far as catching quiltcam - they are now available through Youtube, so if you can't watch them as they are live, you can always go there to watch when you are able.
I'm a huge fan of Bonnie's. If you haven't seen her website and blog, I think they are well worth a visit; there is a lot of free information and scads of free patterns. (
www.quiltville.com, which will also have a link to her blog).
