The long period of sunny weather we have experienced in the Highlands this year, starting in April, seems to have increased the number of birds striking the house windows. The angle of the light hitting the windows, the light intensity and how bright it is in the room, all have an effect on how transparent the windows look. The birds, presumably, don't see the glass and believe they can fly-through the gap. I was dismayed when a juvenile song thrush (Turdus philomelos) struck the sitting room window, and died. I had to do something to combat the problem.
My journey began when I was searching for a way to produce some lined paper, with a very particular layout, that my girlfriend could use to practice her calligraphy skills. Initially, I investigated some graphical applications with the usual point-and-click interfaces such as GIMP, Scribus and Inkscape. As excellent as all these applications are I found it was tedious using them to create a precise, repetitive layout that was likely to need refining many times. A typical problem is: realising that you made a mistake when drawing line 1 when you are already on line 44 and all previous lines now need to be shifted.
