Here is a link that might be useful: Seed tape discussions

I just tried gluing seeds onto newspaper. Kept it watered very well, and radishes and beets are sprouting.

Seems to be working well!

I use toilet paper - each square is 4" so I use say 6 squares for a 2 foot row - fold it in half longways put a tiny dot of Elmer's glue on the bottom half, a couple of seeds, and fold it back over so it kind of glues together, spacing the seeds the proper distance apart. It worked great especially for my carrots since their seeds are so tiny. I sowed some seeds without using seed tape and fewer seeds germinated, and I suspect some got washed away when I watered... I just made more seed tape for my carrots the other day.

The toilet paper goes away eventually.
