LOL!! I had to work today so this is my first chance to explain! LOL!!!
Ok, I took this image:

I removed the white BG and then copied and stacked, copied and stacked and so on until I had it pretty long.
You can download the twisted marshmallow rope here:

I then created the letter I wanted my marshmallow to be in...
I moved/opened my rope into this document and used
transform to size the rope and then the
Puppet Warp function to form it to the letter.
I started at the bottom, but I suggest you start in the middle so that the rope will cover up the middle section and appear to be going behind the down stroke.
I then used the eraser (which I almost never do) and I trimmed off the excess. If you start in the middle you won't have to do this.
Lastly, I used a layer mask to clean up the ends.
You will have to do this for each letter and then move them into the final document.
I hope this works for you! Good luck!
