"Skeleton leaves are real leaves that are dried and treated so that the epidermis is removed, leaving behind just the “skeleton” of veins, then dyed. Skeleton leaves add both a lacey texture and a natural element to all paper arts and can even be stitched into art quilts!" I found this on this site: http://www.artisticartifacts.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=A&Category_Code=skl&gclid=CI3l1Pm2irYCFTORPAodIB8A-g
ohhh yes, these are ones they do some type of chemical process to them to get the color out of them and then die them whatever color they want them to be. i've seen a couple other listings for them on listia, but not many!
