I always sow my tiny seeds too close and I'm not good at thinning, so I'm tempted by the seed tapes for lettuce, greens, radishes, carrots, etc. But I'm too cheap to pay the price for them--I found some instructions on the web for making them. But I'm curious if anyone has tried it and what worked/didn't work for you. From what I'm finding you can use tp or paper towels and either a flour or cornstarch with water as the glue factor. thoughts?
