I refuse to throw them away. They work perfectly fine, and I don't want to fill up the trash with a bunch of perfectly good pens, and then go spend a bunch of money on pens I like better. Because, let's face it, they're just pens. But on the other hand, life is too short to always use a pen you don't like. So I'm really excited to imagine these second-rate pens being turned into flower pens.
The best pens to use with your DIY flower pens are ones with caps (although owning said cap isn't necessary - lost caps aren't a problem). However, I decided to turn some click pens (with the little how to get australia whatsapp number button on top) into flower pens as well, because for some reason we had a lot of them around the house. I'm all for getting creative and working with what you already have when possible. If you're buying something specifically for this project, a capped pen would be your best bet.
DIY FLOWER PEN TOOLS
You will need something to cut the flower stems down to size. I prefer to use wire cutters, but you certainly don't need to go out and buy them if you don't already have them. A sturdy pair of scissors and plenty of pressure will usually do the job. Please be careful with your fingers.
