These are stickers, printed with Canon ink on waterproof glossy or waterproof matte sticker paper. They come in three sizes; 1", 2" and 3".
I created a shaka reaction bubble for my other piece "Da Bus" and it inspired me to create more reactions tailored to different hand signs.
I illustrated these in Procreate. For stickers, I transfer the PNGs to Photoshop and create an entire sheet that I can print/cut with my Cricut. This will be printed and packaged personally from konekokaci’s apartment. Stickers are covered with recycled paper for protection and shipped in an envelope with board backings. I may need a few days to let the ink set + get to the local post office. :)
