how to take measurements for a cover

I personally feel that the best fit in a diaper or diaper cover will be achieved by taking measurements of your little one. then comparing to the manufacturers measurements OR having a custom sized diaper made.
weight measurements are great ... sure, but i do not shop for clothes based on weight or age...
what it really depends on body habitus.. the way you carry weight.. every BODY is different 
as an example a 120lb woman that is 5' 0" is going to look much different than a 5" 9" 120 lb and wear a different size.
so... in babies... a 20lb 6 month old is going to have much different measurements than a 20lb 18 month old

tips:
- it is best to take measurements over a diaper, preferably a fitted or prefold that you plan on using with the cover. if you do not have a diaper handy add 1" to the rise measurement to accommodate the thickness of a diaper in that area

- also while measuring be sure to have the tape measure against body, but not tight that it presses into the skin/fat of the area.

items needed:  
- a pen and paper for noting measurements
- a tape measure. if you do not have a tape measure, you can use a piece of string yarn or ribbon. mark or cut it to the length and then measure on a ruler or yard stick

i am going to show and explain waist, rise, and thigh measurement.

waist: around the belly at about the level of the belly button
