Well, there are pros and cons alike:
- You can make something that nobody else has, and it will be a true original unworn by anyone else (unless you publish the recipe). There's nothing like someone telling me, "I love your polish," and me replying, "Oh, thanks! I made it myself!"
- There are several wildly popular indie polish designers whose creations are either very hard to get or incredibly expensive. If you, like me, only make polish for your own personal use (and the occasional gift), there is absolutely nothing unethical about duping them (or making near-dupes) on your own, as long as you don't try to pass them off as the polishes that inspired you.
- If you're a crafter at heart like I am, you just like to make stuff! I love nail polish, and I love being creative, so this is right up my alley and my favorite new-found hobby. Not only am I doing something that I consider fun and interesting, it's also very useful, as I can wear what I make once I've made it.
- In the end, it's cheaper to make your own polish. With indie polish going for anywhere from $8.00 to over $20 per half-ounce bottle (and this isn't counting the bottles that get bid up into the hundreds on eBay), it's a lot more wallet friendly if you DIY. The only thing about making your own polish is that a small amount of glitter goes a LONG way, and if you're only making for personal use and not to sell, you will find that you'll have a LOT of glitter leftover. You may spend anywhere from $3 to $6 for an ounce of glitter--and realize that depending on a particular recipe, you can make several DOZENS of bottles of glitter with an ounce. You may find that you have glitter just sitting there until you can think of another way to use it. And if you're making only a few bottles at a time, you may never use it all, which could translate as wasted money. But assuming you only buy the amounts of glitter you need and use it all up, it's WAY cheaper than buying someone else's polish. Say you buy $48 worth of glitter--let's just roughly estimate that this will get you 12 half-ounce varieties of glitter--which you will be able to mix and match to your heart's delight. Say you spend less than $20 for roughly 16 ounces of base (which will give you a whopping 32 half-ounce bottles of nail polish). And let's say you pay fifty cents each and purchase 32 bottles. You've spent less than twenty dollars on bottles and polish. Altogether you've spent less than $100 for supplies, but you can make at least thirty-two bottles of polish.
- While the individual elements of polish design are inexpensive (bottles are cheap, glitter is cheap, base is cheap, etc.), the cost of supplies can and will add up. Chances are, if you start off like I did with only a dozen types of glitter, you'll eventually want to buy new glitters--it can be addicting, and I've had to put myself on a "glitter ban" several times because I was buying too much and not using it fast enough. Likewise, once you have tried one type of bottle, you might see and want to try a different type or size.
