Cathedral windows

So, here's what I am teaching today.  This is a class in cathedral windows, that mixes machine piecing and handwork.   I use Lynne Edward's book Cathedral Window Quilts.  Really, what I should be doing now is working on a report for my church's annual meeting but this is more fun.  

This is a small piece, with little purpose except to practice the technique.   I started another piece in a batik; I'll post after I get a bit more done.  Off to teach...
