I no way am I better... I also have this box full of finished projects which need sewing together or which need yarn ends to be sewn in. HATE! I do not know why I despise this so much.
So, I am not able to help you with the yarnends. I already thought about outsourcing this task (... you remember my friend Silvi :-D)
Did not @crosheille had a technique involving glue for the yarn ends?? Perhaps this would be faster. But I guess I cannot glue the sleeves together, or can I (imagine a crazy laugh in the background)
