Back Wrap Cross Carry with Rucksack Straps
Instructions for BWCC w/RS (Back Wrap Cross Carry with Rucksack Straps)
Back wrap cross carry is an extremely supportive back carry, with three layers of fabric over baby and the straps going under and then over your shoulders for amazing comfort. Back wrap cross carry does require alot of steps and can therefore be a challenge to learn and perfect, but when it’s right it’s awesome for long carries. It also situates baby low on your back, rather than up by your shoulders, and so it is not right for all situations, but it is a lovely carry to wear a sleeping baby in. 
In this BWCC variation, Rucksack (backpack) straps are used. Rucksack straps are nice in that they put no pressure on your chest. Also, they save quite a bit of fabric and so you can use a medium length wrap. They are also helpful if you are planning on laying baby down after he/she falls asleep as the straps can easily slide off your shoulders, instead of you being tangled in the wrap.

First, assemble your tools.

That is the cutest baby I’ve ever seen. What a neat technique. I’ll have to try this out as soon as my sisters’ twins are born. She’s gonna need the backup. :3
