The changes to the angel were to leave out the bows and replace with a headband of red chain stitches.
The shepherds were more original, though not much. The head cloth came from the Nativity Set, minus two rows of garter stitch at the end. The hair came from the angel/fairy but inside out and a row shorter. The beard is from the Nativity set, minus 2 rows of garter stitch at the end. I hope that's clear enough. I don't want to go to the trouble of gaining permission to write up the whole pattern in detail. Email me if you have any questions or ideas.
