Sure! A few quick pointers:
1. the edge of the fabric that is at your outer shoulder needs to stay the bottom/inner edge all the way around. Making sure there's no twisting is very important with an unpadded ring sling. So that edge is the bottom edge all the way across your back, then at your waist it becomes the edge that you bring up against your body to form the pouch for the baby.
2.Also, make sure you are staring with the depth of the pouch about where you will want it, rather than having the whole thing very loose and then trying to bring it up with the baby in it. Start with the rings slightly higher than you want them (the corsage position is where you want them). Once you get the baby in, make sure you support his weight as you adjust. His weight locks the rings together, so lifting him slightly will allow the rings to open for the fabric to slide through.
3. When you adjust, make sure you are pulling each section of the tail separately to adjust only where you need it. So pulling the inner edge of the tail should adjust the outer rail, and pulling the outer edge of the tail should tighten the bottom/inner rail. For this to work, the fabric must be spread correctly in the rings. The outer edges of the fabric should be at the outer edges of the rings/tail. Before putting your sling on, find the two hemmed edges in the tail and pull them away from each other toward the outer edges.
4. To get into a good nursing carry, try putting the baby in a t-2-t position first. Then loosen the sling enough to let the baby's head and body lean over toward the breast opposite from the rings. You may want to reach in and place a hand under his bottom to scooch it down and pull his legs out from under him if you want him in more of a cradle position. Bring the outer rail of the sling up around his head to support it. Keep it loose enough to allow you to get the baby latched on, then gradually tighten it so it supports the head at the breast.
Another good way to learn to nurse in the sling is to put the baby in a cradle carry with head opposite the rings, then loosen it a bit and sit down. Keep the sling loosely around the baby like it's just a blanket, and latch him on as usual. Then tighten the sling enough to support the baby at the breast. Gradually try standing up and adjusting as needed to allow you to nurse.
HTH, and please do post some pics if you can, or ask more questions. You have a good sling, and I'd hate for you not to be able to use it. Oh, and you know, I think Darien has some video clips showing how to do this at www.zolowear.com
, and the shoulder on the Zolo is similar in style to the TMT, so it should help.
