I just did an Accessories Club on this very subject. Be sure to include these--
buckle card with the word window punch
scalloped edge with the slit punch
froggie made with the oval punches and those googlie eyeballs
giant daisy with the oval punch
tabs with the circle punches folded around the edge of a card
faux metal rim tags with the circle punches rolled in Versamark then emboss
longer tags using the tag punch with the paper pulled out the bottom
sea waves using the edge of the large oval punch
Using twine or linen thread through the notched corner punch
using the 1/2 in circle punch as a corner notcher
1/2 in circle punch as a hole protector thingamabob
layering the flowers from Spring Boquet punch with a brad
Those are just a few! Hope that helps! I had two hours worth of things to discuss, demo, and do. There's also a punch chart that you could have them make. It's in the demo SUB gallery. I'll try to post my four projects today so you can see them in person--one card used 12 total punches.
