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. Glue the two side flaps, fill with seeds, fold the top down. Keep packets somewhere cool and dry — and label-happy: future-you never remembers which chilli was the scary one.
