clem, it's not difficult! Honestly, it's not. My best recommendation is to take some muslin or inexpensive fabrics that you won't be too concerned if the cuts are not immediately perfect, and just start.
There is one thing that really gets me, though, about these TV quilters, in that I see them just putting the selvedge edges together and doing the rotary cuts. What they don't tell you is that the selvedges don't always run perpendicular to the cross-wise threads of the fabric. So when you cut, you still end up with wonky cuts sometimes.
Maybe I need to do a tute on this? At least show my method? I've never done one, so don't hold your breath, but I'd be willing to try it ...
Happy quilting (errrrr, I mean, "cutting")!
