The hoops measure 4.5cm across.
They have a curved edge on either end, to add an earring post drill a small hole and use an earring pin or you can sand one of the curved edges flat and attach a flat earring post that way, you will need a 3mm post if you do this.
Please do not use heat such as lighters on these moulds. If you need tips on how to
avoid bubbles in your work, I cover this in my online Domestika course.
Please allow 1-2 weeks before dispatch.
