Windows and plaster

This is the new window in the main guest bedroom that i have put in. As you can see it now requires the wall around it to be plastered and then hey ho it is done. I know that it doesn't look vertical or horizontal but it is an elliptical elloption. Really it is!
It is very difficult working with 1metre thick loose stone walling held together with mud packed between the joints.
It is even more difficult trying to plaster. My arms are aching like mad and i swear more is splashing on the floor than going on the wall. The dark bit above the window is an original solid chestnut beam which we uncovered when taking out the old window and removing the old lathe and horse hair plaster. It has cleaned up really nice and will be left exposed along with the beams which used to have a ceiling attached to them! As you can see, just outside the window is a beautiful old pine tree which provides a great perch for all manner of birdlife including two varieties of woodpecker.
Having now rested my arms a little i shall return to my torture....more plastering..i will post a picture of the finished window area complete with new window ledge made from reclaimed chestnut flooring. (made from offcuts of the original floor)
My arms i am sure are now inches longer than they used to be, plastering is very heavy work!
