These Guide Stickers have been a god-send. I do my own acrylic nails and bc I am right-handed I often mess up a little while doing my right hand nails with my left hand. Usually I notice the acrylic is too thin on certain nails and I have to go back and add acrylic. Using these stickers have made adding acrylic much easier and allows me to be a bit more precise. B4 I had these stickers I would add acrylic and then move my hand around to keep the acrylic in place until it dried. I've also attempted to manipulate a sticky note around my nail so that I could add acrylic but it didn't work as well of course bc the sticky note isn't shaped to form around the nail. If you're a newbie to doing your own acrylic nails, or if you're experienced and want to make sure the nails are created equal then I definitely recommend these guides.
