Rotary cutter revelations

I am somewhat of a sceptic when it comes to technological advances - I have an ancient Nokia mobile phone, I wind the windows of my car open and shut by hand and my sewing machine dates from the early 60's. And when it comes to patchworking I cut fabrics with scissors, that is I used to and then a couple of Christmasses ago my husband gave me a rotary cutter and a quilting ruler. My life was transformed!
Rotary cutters are basically pizza cutters but for fabric and used in conjunction with a cutting mat and a quilting ruler you can produce beautifully straight and accurately measured cuts.
Mine is made by Olfa and measures 45mm diameter and my ruler is 24inches long and 6 inches wide and is calibrated every which way - joy!
This Saturday I am giving a demo of machine patchworking, at Sew Patchwork in Thame, which will include how to use a rotary cutter and I have been busy making up samples to show some the different effects you can create quickly and easily using strip patchwork.
Lovely simple technique!
