Every seed packet template on the internet is a blank PDF and a suggestion that your handwriting is neater than it is. This one does the writing first: type the variety, sowing window and notes, and print a fold-up packet with everything already on the front. One packet per A4 sheet, cut on solid, fold on dashed. No signup, nothing uploaded.

Plain paper folds easiest; 100–120gsm feels like a real packet. To assemble: cut around the outline, fold the two narrow side flaps backwards, glue them, then fold the big back panel up behind the front onto the glued flaps. Fill with seeds, fold the top flap down, tuck or glue. Keep packets somewhere cool and dry — and label-happy: future-you never remembers which chilli was the scary one.
