Cloudy, but sunny, with rather a strong breeze, and I got cold outside, so had to come in two times to add more layers before I felt comfortable.  It was the wind that made me cold. 

I had decided on the method of construction - saw a 45 deg. angle into the top of the header, chip it out with a wood chisel and hammer, then screw the 2x2s in to the header at a 45 deg. angle.  Bip-bip-bip - the sound of a woman screwing, I laughed to myself, at a 45 deg. angle at eye level, with screwdriver over my head.  What a lousy job I did, but I got the header up and all the 2x2s are solid, if extremely unprofessional.  The whole thing is designed to be taken down in a jiffy, anyway.  But looking at the construction so far, I realize that I needn't have bothered with all the 45 deg. angle stuff - I could have just put the 2x2s on top of the header and forced a screw in through the gap.  Live and learn...

Well, the frame is up and all the rippled plexiglass fits onto the 2x2s.  I made the frame to fit 4' 6" high up on the wall of the house.  Now to construct the front wall of the greenhouse, which I think will be 2' high by 10' long, the width of the greenhouse.  That will give a good slant to the plexiglass roof.  Then I'll dig a trench through the middle of the greenhouse, so I won't have to crawl around to tend the plants.  The front part, where it will be 2 or 3 feet high, will be for small plants and starting seedlings.  The trench, depending on how deep I dig it, will give me 5 to 7 feet high of clearance, and the back wall by the house will be 4 to 4-1/2 feet high.  The reason I didn't make it taller is because it is built right in front of my picture window in the bedroom, and I don't want to give up being able to see most everything out of that window.  Right now, it is taking up only 1' of viewing off the bottom of the window.  And the whole structure can be moved to another part of the house, if necessary, where it can be made taller at both the back and front.

So, back in the house for the day, telling my many baby plants that soon, they will have a better home.  All I have to do now is figure out what is the best way to attach the plexiglass panels to the 2x2s - small screws?  small nails?  this will take some research - glue?  I may want to put chicken wire across the top to add strength before putting on the plexiglass, which is pliable, brittle, and might be broken easily...come to think of it, I'm not sure it's plexiglass, I think it's fiberglass panels.  Oh boy...
