Wow, you only have 1 punch! Sounds like a great bundle for you!!
I love the word window punch and modern label punch.
Also love the medium and large oval and scalloped oval (sorry not sure the exact names without the catalogue in front of me, but they layer well together).
I also love the bird punch and decorative label punch!
And I use the boho blossoms punch a lot (or some other type of small flower punch) and the heart punch. Circles are always useful!
I really find punches and dies a good investment because I use them over and over. And often then can have a dual use (punch art).
Have fun punching!
