Ingrid, Not sure what you mean by "definite stripe to follow", but...
I was working with black yarn so I used bright pink yarn on the tapestry needle so that I could see it easily. I also get paranoid about making mistakes so every couple of stitches I checked my pink "stripe" to make sure it was following the destination row. Usually I could even see if the pink yarn was crooked, meaning I picked up a stich from another row. If you do happen to make a mistake, just go ahead and pull the (pink) yarn out back to your mistake, and no harm done. Key word is PATIENCE!
