Sewing AIO

There are several good website that gives very good instruction on how to sew AIO. When i first learn to sew i used a few instruction sites as reference. Hope mine can give you some helpful tips.
For AIO nappy you will need PUL fabric or any fabric of your choice with a waterproof layer. You can use procare (i find this a bit bulky), PUL, ripstop (it's a shower curtain material). Then u can use bamboo/hemp/flanellete/cotton as soaker/booster, As for the inner top layer more popular choices are microfleece/suede as it keeps skin dry but u can choose any fabric for this as long as it's absorbant.

Before you start u will need to get a pattern, your fabric an outer layer (fleece or PUL), a waterproof layer if u have an non-waterproof fabric as outer layer, and an inner layer or microfleece or suede. Elastic, velcro/hoop & loop or snaps (requires a snap machine). Soaker material can be cotton flannelette, bamboo or hemp fabric.

After you've have cut your fabric, sew your soaker/booster first. I prefer not to hide the booster so the nappy will dry faster. For a beginner, if you hide the soaker, your nappy will look much nicer as all the mistakes and rough stiches are hidden. Attach soaker to the right side of the stay dry/inner layer.

This is a PUL cover so the less you prick the material the better to avoid leakage. In this case, i use pegs or u can also use bulldog clips.

Sew loop at the front or right side of the PUL fabric.

This is another version. I use a microfleece as cover and use ripstop (nylon material) as the waterproof layer which is cheaper than PUL and u can get it from the stores like Spotlight . Some people told me ripstop fabric will wick but for day use i think it's fine.

I cut up about 3 inches of PUL and use it to cover the back where you can see the stiches after sewing the loop. This again is to prevent leaking. Then pegs the wrong side of both pull and microfleece facing out. You are going to sew around the edge and turn it around later. Leave about 10 cm opening at the belly.

When u are done sewing the around the edges. Use zigzag stitch to sew elastic on the legs and waist. Your patter should show you the start and end point where the elastic should be. I sew on the microfleece side so it'll roll inward.

When you are done, turn the right side of the nappy out and topstich the opening at the belly. I prefer not to topstich the whole nappy as i was advised by some people that more stiches or holes on the PUL fabric will make it wick. Last step, is to sew hooks on the tabs and you can sew loops next to it as laundry tabs.

I sew another removable booster toped with microfleece so it keeps baby's bum dry. It's your choice to sew your booster square or with contour. I am just too lazy to create more work. :)
