I agree with Tartan, get the large one then use a 50% or 40% off coupon from Joannes or Hobby Lobby or Hancock and get the fussy cut pack of rulers (5) Fons & Porter then put them on top of the Twister ruler and trace the lines on them...you'll then end up with a 2 1/2, 3 1/2, 4 1/2, 5 1/2 and 6 1/2" rulers to cut out the twister patterns. I thinking that group of rulers cost about $18. to $20. so use a coupon!!!
