I was contacted by a pin and patch subscription box curator of BratBox a couple months ago to have my pin added to April’s box. I was/am completely honored and thrilled that someone wanted to use my design.
If you are low on funds to purchase your enamel pins, I recommend using Kickstarter to fund your project. Start small and budget for some good perks and stretch goals if you can. It can be hard, and let’s face it, there is a chance of failure. But the thing about Kickstarter is that if you’re not funded, there is no loss to you (besides your time). And you can always try again.
