This is the desk top. It folds up. The picture shows the hinged legs and that the top is also hinged.
When you unfold the legs & lock into place, the smaller hinged section of the top locks into the top of the filing cabinet section where the raised strips are. When you don't want the extension part set up, you fold the legs back in and then lower that part. I did not take a picture of that to show you. It goes down to about the size of the filing cabinet itself. There is a second filing cabinet just like the first. I don't know if there originally was another desk top or if someone just had a separate filing cabinet. The extra one will slide underneath the back extension of my big Bernina sewing table. The drawers can hold sewing supplies.
And see what sewing machine I set on top of the new table/desk cabinet.
Ignore the mess around behind the desk. I had to move several crates along the wall so that the desk could be set up. That required some other things to be moved. You know how that goes. I have to get everything organized again. The crates had wool in them and they will go back into the guest room closet where they started out in the first place.
I was working on a patriotic wall size quilt but am abandoning it. The center blocks are composed of string sort of pie shape sections. The instructions said to sew strips onto a fabric backing. It is all just too bulky and way too much with eight pieces coming together into the center. I just wasn't happy with it after making two blocks. The quilt instructions were very vague also. I want to be satisfied with the end product and feel I can do something better. So back to the drawing board.
Have a great day!
