Forgive me but I cannot seem to find the thread. One of the luvverly mods suggested to another poster (asking about making a striped scarf) that they don’t tie off but carry the yarn up (to avoid loads of weaving in of ends). I asked a question about that and the creation of a ‘loop’ of yarn at the side that this would leave. I would not do this if I was making a broader stripe but I can see the sense if say you’re only doing one or two rows of another colour, but, that ‘loop’ bothers me 
Is that avoided in some manner? If i was making something with panels I can see the sense in doing this as the loop could be slipped between the seams…but…on an item like a scarf???
