Resin for Beginners: A Handmade Artist Answers Common UV Resin Questions and Shares Recommended Products
Common UV resin questions for beginners, answered by a handmade artist
Hello, this is Kanahina ☆
This Q&A guide is for beginner handmade artists and anyone who has just started making resin accessories. UV resin is easy to try because materials can be found at 100-yen shops such as Daiso, Seria and Can Do, but beginners often have questions about curing, bubbles, stickiness, yellowing and safety.
I will also share an Amazon link to resin products I often check when choosing supplies 😊
