Free printable: pop-up cactus garden postcard

I have a free printable project for you, a sweet little pop-up postcard you can send to friends or family. I have had a lifelong obsession with cacti, I think it began with this book, a favourite of my childhood. So I plan on sitting this next to my computer, having had no luck at all with real-life indoor plants!

I haven't added anything extra in this tutorial, apart from cutting out the cacti. But I would love to add some tissue paper flowers, or washi tape to decorate the pots.
