When you start crafting, sometimes the key is versatility, I ask myself how much will I use this? Is it worth it?
One of the stamp sets I use alot is Gorgeous Grunge, it is has so combinations that can be used. I love it either on its own or with different sentiments.
If you look on Pinterest there are so many amazing examples, I tend to Pin them and then try and make my own version.
I definitely recommend that it is an amazing set for every stamp collection.
