Having been thinking about the name of that German lady, and suddenly it popped up...
And since you're called Andrea here, I guess you're one and the same? Andrea Stracke...
It were two very inspiring days then... And although I went back to the rocking stitch, that workshop is still inspiring my quilting designs.
So I have been so lucky to see your work in real life (on that workshop, and on the European Quilting Championship in Veldhoven, the Netherlands) and it is truly amazing...
