I'm still not 100% sure I will offer a full buckle but I am having fun experimenting. This full buckle is made from a cotton jaquard fabric. It's not a wrap but I love it. The fabric is so soft and has a nice feel to it. It would make a nice summer wrap I think (but I have too many of those already!).
I decided to try a semi structured waist - a stiff foam in the middle and soft padding at the sides. I find it quite supportive but I think I still prefer a padded waist a bit more. I'll see what I think of it as my son grows (he's almost 10kg now). The top folded over slightly when worn at my waist but didn't when worn at my hips. Perhaps it's the shape of the waistband (which I don't want to change as it works really well for me). I'll see what I think after I have used it more. It bends far less than the foam I first tried anyway.
This carrier is a baby size (4 - 18months). It's a slightly smaller size that the mei tai baby size since it's harder to modify by rolling or scrunching like you can with a mei tai or half buckle. It also has seat darts which help to direct baby's weight onto your waist/hips. The darts are shallower than the toddler size so baby is still held quite close to you.
I love to sew. I have five curious and active kids who keep me busy!
