first you get a 13cm object (it doesnt need to be exact)i used a book .
then you wrap your wool around about 70 times (loosly).then pull it off and get another small piece of wool and tie it round in a double nott .

next cut another piece of wool and tie a double nott about 3cm down for the head

now find a 7.5cm object (again not exact) i used lego pieces. this time wrap the wool around 18 times .

then pull it off and tie a double not at both ends to create the hands and arms.

after that insert the arms into the middle of the body and push them up to the neck !

then tie a piece of wool tightly around the waist (right under the arms). make sure you use a double nott

now cut all the loops at the bottom. if your creating a girl leave it like this (if ur creating a boy carry on)!

if your makeing a boy, then split the bottom in half and tie a piece of wool round each in a double nott to create some legs (this could be done for a girl doll).

now your done!!
i hope it came out right. if you want you could make some felt clothes ??
