SIMPLE LACY SHELL TOP
Nearly.. because it’s always neater to finish off with a round of sc. So re-attach your yarn at the neckline (any corner will do) and work a round (or two?) of sc all around. Similarly work a round (or two) of sc all around the armhole edge too for a neat finish.
You can make the sleeve length any length you wish, as long as you remember that you are working in a round, and so you must check that you work with the largest round measure (i.e if the upper arm measure is the largest, then that is the round measure you will have for the full length of sleeve... Got it?)
Of course, this also depends on your skill level - and you could well decide to tweak the pattern a bit to get the sleeve shaped too.. if you do, hey have fun.. and if you'd like to.. do share your ideas as comments here, and I will edit it into this blog if you'd like that. Cheers.
