The first method is what we would all use, a straight border across the top and bottom. The Stampin' Around Wheel Guide is a really clever gadget to make it dead straight. It's a neat ruler that's invaluable if you use your wheels alot like me.
The Second method was to create a frame with perfect mitred corners around a page. I've done this on the chocolate chip cardstock. Again I used the Wheel Guide to help me with this and I have to say it's brilliant. Full instructions come with the Wheel Guide (a bargain at £6.95) and it can be used for both the Jumbo and Standard Wheels.And thirdly I wheeled over a complete piece of cardstock to make my own unique patterened paper shown on the centre piece of Very Vanilla which has been matted onto the Bashful Blue cardstock.
So if you've got these wheels and don't use them as much as you should, get yourself a Wheel Guide - you'll love what you can do with it!
