Hi wt1,
The first philatelic advisor to King George V was John A Tilleard MVO, later followed by Sir Edward Denny Bacon KCVO as Curator of the King's Colllection. From what I have read their duties included finding, arranging, mounting (with hinges) the King's stamps, and annotating the collections. The King might pop in at the end of the day to admire his latest acquisitions and the pages newly written up for his albums. I suspect it was much the same during King George Vl's reign.
Queen Elizabeth ll keeps the Royal Collection going and is shown, for her approval, each new issue from Royal Mail, though I can't imagine she is too overwhelmed by much of the stuff they put out now.
Best advice for writing up in ink using either dip pens, or the excellent Rotring Calligraphy ArtPens 1.1, 1.5, and 1.9, is to lay out the page with notes lightly written in pencil, then carefully ink over. Only when that is done, and the ink dry, mount the stamps in their appointed spaces.
If you need to improve your handwriting I can strongly recommend this site
http://www.operina.com/Download the excellent free zip/pdf for 'Handwriting Repair' , fifth down the blue list. When that opens click on 'download free repair zip'.
The object should be not to perfect an elaborately perfect 'calligraphic' style of penmanship, but to achieve a consistently neat and clear handwriting style. Of which an Italic style is best of all. So it is written.
