Using SU Slit Punch
 

I purchased the SU split punch with big eyes, but now I can't get it to work. I'm definitely mathematically challenged. How do I line up the slit so that it's even on all sides? Thanks in advance!

I need help with the slit punch too...I can't get it to work for a scallop border??? Thanks!

ditto!

See Andrea Walford's website, under Tutorials, there are Techniques, where she has links to a couple of Tutorials about using the slit punch for borders and such.

Here is JulieHRR's thread for using the slit punch: http:////www.splitcoaststampers.com/...punch+tutorial
To make a scallop border with it, you have to take the guard off. You need a strip of cardstock. The scallops will be punched onto the opposite side of the cardstock.
