I usually wear my mei tai 'apron style'. This is where you tie the carrier around your waist like an apron. The print you want to show when the mei tai is worn will be towards your body. This is the method I describe in my instructions. When sitting in the mei tai the baby's bum will sit below the top of the waistband in a pouch made by the mei tai. There is another method you can use to tie your mei tai around your waist - the non-apron style. Tying this way distributes baby's weight differently. More of your baby's weight will be distributed towards your hips. You can tie around your waist or at the top of your hips. To tie this way hold the mei tai with the print you want to show facing towards you. Then fold the waist band under once and tie around you waist. Put your baby in the mei tai with your preferred method and tie on as normal. The whole waist band will sit below your baby's bum (see picture below) allowing it to direct more weight towards your hips. Tying non-apron also lengthens the body which allows you to get more use out the mei tai if your baby has grown too tall for that size. I think there can be more weight on baby's legs with this method though which is where leg padding is useful. (But not for wrap conversions as the fabric is already soft)

An exampe of apron style - baby's bum is below the waistband. You can't see any of the waistband under baby's bum when the mei tai is worn.
I love to sew. I have five curious and active kids who keep me busy!
