Ask for a grid, not stickers.
If you say "sticker," the model bakes in white outlines you can't cleanly separate later. Saying "4×4 sheet" works better. The builder already does this for you.
What you can make.
Pick a character style, set the language, pick a text style. Type your sixteen phrases or grab a starter pack — or switch to Emotions for a text-free sheet of pure expressions. Copy the prompt and paste it into ChatGPT or Nano Banana with a photo of yourself attached. The model gives you a 4×4 sheet — bring it back to GridSticker to crop the cells into chat-ready stickers.

Attach your photo in the chat — same photo each time. The prompt tells the model to use it as the character reference, so every cell looks like you.
Pure white works best for GridSticker's Remove BG. The outlines and per-cell crops happen after the model is done.

Open the sheet in GridSticker and drag the dividers by hand. Smart Slice catches most cases. For the rest, the per-cell drag does it.
Bump the tolerance slider in Remove BG — it handles cream, eggshell, light gray. If it's actually a colored background, switch to Smart subject.
The prompt above already tells the model not to. When it slips anyway, the erase brush in GridSticker wipes them off cell by cell.
Tap the bad tile and adjust outline width or tolerance just for that one. The other fifteen don't change.
