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 don't often sow in blocks so only need to mark rows of veg. I'm lucky to have a supply of grey 18" long bits of robust plastic tube, originally the centre of fax rolls from the weatherman next door (now passed, as well as the fax machine I expect). These tubes mark position and I use 6" white plastic labels and some 5" yellow ones from Premier seeds, written on with permanent marker. The tubes last forever,  the labels get scrubbed up for use next season. I also have a scribble book in my garden bag to write what I've done and various books indoors.  Even then I forget
