Very nice, Karen. Quite striking and definitely not red. You used the Stitch Witch stuff, then? I've seen it in stores (the search for raw materials for my 'projects' takes me far and wide), but not knowing how durable the stuff is (and not really having a need to mess with it so far) I've not looked at it too closely.
Regarding the size, if you want to add them as attachments (rather than in-line images), it'd be more merciful on the lower-bandwidth MobileReaders.
