question about finger hash

i got some keif saved up it really isnt much but i read that u can make it in to hash by rubbing it into your palm and so forth.please tell me if this is true i do not want to waste my keif if it doesnt work

u can make finger when u trim your harvest to make a bud with no leaves. the resin sticks at your fingers and u collect it. u dont have to waste anything to make finger just a lot of weed. finger is like a ix of red hairs and thc resin or whetevr. really really good and stoning :)

i have just pressed a lump of keef in between my finger and thumb until it started to stick togather and rolled it around until it was a small ball and it worked fine.
