Those are some amazing stickers! Have you ever thought about selling stickers and whatnot on Etsy or RedBubble?
I do sell some on the side, mostly to randos on 4chan and people from discord servers. Ive considered etsy and bigcartel but haven't gone through with that yet. As for redbubble, i think they only sell stiff they make, you can only really input the design, and they use low quality material.
(i made the image bad quality so its harder to see all the bubbles cus im bad at applying)
