2023 - What I sowed today

What do you all use to mark your outdoor sowings? Last year, I mostly used little markers made from old yoghurt pots and similar, but my garden is quite exposed and the wind moved them around. I have some slate markers, but it's hard to write on them clearly, the chalk washes away quite quickly, and they snap very easily. I'm currently marking the corners of blocks where I've sown things using twigs, but as I get to the point where most areas have sowings, that's going to become less clear. Even now, it doesn't tell me what is sown in which block. Maybe I should draw a garden plan and mark sowings on there? But I can't do it outside in the wind and I may have forgotten where I sowed things by the time I get inside!

I use my phone and take a picture of the area and either take a photo straight after planting of the label/bag/seed packet... or edit the photo and write a note. Then sometime over the following few days draw it out in a book. I dont use any labels in the garden....except for dahlias...each one geta a tag around its stem.
