Looking good Rob, and it's going to be impressive when finished.
For future reference, one way to possibly prevent, or at least reduce, the pixelation effect when reducing the image, is to try to start off with either a very small image to begin with, or, going the opposite way, with a large, very high definition image, and reduce this in a 'Word' document. For example, if you were able to scan, or photograph, the relevant required section of an Air Navigation Chart, this could be printed, or saved, actual size - say the equivalent of 8 x 10 inches.
Alternatively, photograph or scan a smaller image, and reduce this to a size where pixelation does not show. This image can then be printed and scanned, so that, in effect, you are now starting with a new, smaller original.
Once this is done, and saved to your 'My Pictures' folders, open a new 'Word' document, and insert the required picture.
Once inserted, click on the image, and the outline box, with the green spot at top centre, and corner 'navigation' spots, will appear. Click and hold on the top right hand corner spot (or whichever 'spot' is easier for you to control.), and 'drag' this spot diagonally downward into the 'box'. You will see the image being reduced (shrinking), and can stop when you have it the required size.
This can then be printed, and using a gloss, or photo-quality paper, will give a better, sharper result.
If you need to duplicate this image, into as many as you want, then this can be done quite simply, again in 'Word', by using a method of 'step and repeat'.
Click on the image, then press 'Ctrl' and 'C', then move the cursor to the bottom right of the image, and press 'Ctrl' and 'V'. The image will repeat, and you will now have two images.
Repeat this process as many times as needed to make the desired number of the same image, at the same size.
Hope this helps.
