You can make your piercing holes bigger by using stretchers. You can get them at just about any piercing shop or shop that sells bigger gauge jewelry. If you’re going to do it, remember to stretch slowly to avoid blowouts. Also, if you decide to go large gauge, your ears may not go back to how they are now. Mine are at a 6 gauge and will go back to piercing gauge if I leave my earrings out. A friend of mine had his to a 0 and they are permanently open. Fixing this requires surgery to close the hole.
