I hope this helps. It has been the only thing that has worked for me
(And, this was my last clean emebllished prefold, so sorry it isn't the best tutorial. this fabric doesn't let me crease it down as much as my other stuff)
Fold it into three with the edges touching
Fold the top down and make the wings (You have to kindof pull the fabric to get the wings to work right for you)
Pull the prefold up and get it to be snug around the legs. Then fold the front either inward (like mine) or outward to make wings again.
Snappi it, and then lift the legs up. If it isn't snug just take one hok off and fix it, then the other one (I still do it almost every time)
YAY!
I didn't do the greatest job, but he was getting mad at me for taking so long.
I can get one of Sarah Stitches' fleece covers and a pair of jeans on him (it is about the same thickness as a pocket when I put a fleece cover on) and he can still bounce and squat and sit.
(I just gmd dark brown edged prefolds, blue edged prefolds, and regular premium prefolds). Sometimes the front fold nunfolds on the brown edged ones but it doesn't change much.
(Also, don't mind the changing cover. I have to sun it, washing it just isn't working)
I didn't want to make a new post
