Check out these awesome fret stickers from FineFun. These are perfect for beginners to help map out the frets on your guitar and are easily peeled off once you’re in the know.
I’ve had some great experiences utilising these with students, and then removing them over time as some confidence is built. If you do try them, make sure you don’t become completely dependent on them! They idea is to get you started, not make you rely on the visual reference.
