My son and I have had a heck of a time getting our seeds going what with our cats eating the tops off all the seedings as they sprout on our table. So i decided we should build a cold frame for those that will be outside soon. (His pot of herbs is staying on the window sill in the kitchen) i didn't know what to use, but instead of going out and buying stuff i thought we should get out in our yard and see what we had to use. So since dh isn't getting working on our new driveway till later in the season, i stole some of his bricks from his brick stacks. and we had a screen door in our crawlspace because we don't want it on a door that we never use. Later we will build a porch on the side of the house where that door is (instead of just stairs) and i will return the screen door. For the seed trays i used empty egg cartons. So it may not be pretty, but i think it will work. Erick sang the "Bob the Builder" song while we were stacking bricks and was so excited to put our seed trays and tender plants into it. I am excited because with the plants outside, i get my dinner table back!!! Nd the cats wont be able to use the seedlings at their personal salad bar at night now either!! We looked online for the idea for the project and took a little from a few sites.
