Today I made my own seed tape. It was soooo simple! It's quite a savings when you compare what it costs for seeds already done and what a regular pack of seeds cost and the amount you get. And best of all there won't be much for thinning this year!!
I mixed up about a 1/2 cup of flour and added enough water to make a rather soupy paste. I used my hand mixer to make it quite smooth, then put it into a ziploc baggie until I was ready to use it. I cut newspaper into 1 inch strips and used a child's medicine eye dropper to dab the soupy paste mixture on it spaced apart according to package directions or what you prefer. I placed my seeds into the dabs, then used a toothpick to push the seeds into the dab. Let dry, roll up using a small piece of tape to join the strips and place in a large ziploc. When it comes time to plant; place seed side up, cover with dirt, add plenty of water.
The pictures show two packs of beets and one package of radish.
I think for next time I might use the flour/water mixture to join the strips instead of tape so everything is biodegradable.
