I've been trying to figure out why the Ravenclaw pattern bothered me.
Ravenclaw's heraldric animal is an EAGLE not a raven.
So I did a little changing again.
1) I changed out Ravenclaw's bird.
2) Made all of the helmet toppers the same, as I couldn't find a good simple eagle that small.
3) I quartered the shield behind the eagle to match Gryfindor's.
4) I quartered and barred Slytherin's sheild.
The last two are so that when you put them in place, to match where they are on the Hogwarts crest they match diagonal.
I also made sure all the color's are consistent throughout all the patterns, so if you want to sew the Hogwart's crest and any or all of the house crests,... you don't have to have four hundred different colors.
