Flemish giants have the same semi arch (mandolin shape) body type as English lops, so I used that pattern, but with upright ears. Most pictures of the breed I found online also have them sporting huge dewlaps, but that's more of a doe thing and this bunny is a buck, so decided to skip it. Also decided to add a super fluffy loop stitch tail just because.
