I get asked this question more than anything else. And I'm happy to say that I outsource my stickers with a company called Stickermule! I do not make any of them at home for a number of reasons:
- The quality I get from outsourcing is better than anything I could do at home
- I have thousands of stickers on hand at all times and that kind of demand would be a nightmare to cut all by hand with a Cricut / Silhouette
- My stickers are high quality, durable, and waterproof
I use Stickermule for all of my stickers. I've used them for 2+ years now and the stickers I got in 2018 are still holding up just fine on my car and waterbottle! I'm able to put my mugs in the dishwasher (but usually I hand wash), and my car has gone through many car washes without scratching or taking off my stickers.
There are tons of other sites to choose from, but Stickermule is by far my favorite company. They ship stickers really fast and their prices are hard to beat. They run sales pretty often on the various products that they make which is always nice.
Even when there isn't a sale on stickers, the bulk pricing structure really helps when I am ordering a restock for all of my stickers!
