I wanted to try out if just a part could have the glitter effect and colored and it was possible. I think though, the colors from the glitter segment could have been stronger if I didn't lower the opacity to 85%. Just letting them know which part would be opaque(with a white layer beneath) and which part would be transparent is fine.
I was worried that I wouldn’t get a quality product based on the price, but it was worth it! The printing on my sticker came out very nicely with vibrant colors! My warning for new buyers is that you should expect a bit of the glitter to peak out underneath your opaque layer, but it’s an amazing addition to your stickers!
The stickers came out beautifully! The only thing is the image is slightly transparent to see the glitter through the image. The image comes out slightly darker, so raise the brightness slightly to account for this and they'll come out perfect!
