I'm so excited to announce my Craftsy Class: New Directions in Tumbling Blocks!


title card


I have so much to share with you in this class!  Often tumbling blocks can appear intimidating. However, you won’t believe how easy it is, once you know how!

We will start learning all the tricks of fabric selection, cutting and piecing Tumbling Blocks by creating a lovely  Tumbling Blocks runner.

But the fun only begins with the Tumbling Block runner!  Next, and here’s the real magic, we will take  tumbling block into a brand new direction!

During the class, I will show you how to create different amazing designs, all with a 3-D look.  You will have fun, learn a lot,  and I will be guiding you every step of the way.

Need to see a step over again?  It’s simple! Each Craftsy class allows you has a 30 second video repeat and allows you to make video notes.    You can watch me demo a step as many times as you wish!

Your Craftsy class is yours to keep – watch any time and as many times as you like!  The class is filmed in high-definition, so you can see all the details I’m showing. . .  as if you are standing right next to me, watching every step.
