I am so new in Shopify. I am illustrator and I have been looking for suppliers with drop shopping:
1. Sticker supplier. Contour cut on sheep. I read about stickerapp
2. Enamel pin. I read in Shopify article about made by cooper
3. Patch.
But are sticker app and madeby cooper like printful? I mean can I add them as an app from shopify App Store, cause I cannot find them. Do you have any suggestion? Thank you
