WOW the new Rotary Attachment for the Stampin' Up! Trimmer is fantastic! I've created a little video which shows you how to change the handle and the blades.
Each blade is $5.50 (when you buy the Rotary Attachment for your trimmer by August 31st from me I will give you your choice of add-on blade for FREE!)
Some tips – when you use the speciality blades (scallop and tiny wave) you might have to press down a little harder than with the straight blade (which cuts through like butter!). The perforating blade is awesome for creating a cute coupon book or a bookmark that you want to detach for a card. OR you can use it as a faux stitching element too!
