I sent Ann Holmes a question about what size rotary cutter the Magic Button fits & here is what she said:
quote:
"it is designed to fit on a 28mm OLFA Rotary cutter.
I use it for 90% of the cutting that I do to automatically add seam allowances.
I also have Magic Button 2.0 for the smaller Applique pieces;
this one fits the 18 mm OLFA Rotary Cutter."
