sowing seeds.

[Appaloosa]

Having moved into my Bungalow and getting my shed set up, I thought I would have a go at growing a few plants and tomato's in my small yard which has been block paved, so am looking at containers etc. I have now got my seeds, but am amazed how small some of them are! I can barely see them even with my strongest reading bins on.
Is there any trick i can use to help with the sowing? I`ve not done anything like this for over 45yrs so i could do with a bit of expert local knowledge and tips. thank you.

Any luck with the seeds?
