Wow you say you are easily bored and present not one but two blankest!! Up today I only managed to crochet some squares which I never turned into a blanket... Perhaps my attention span is even shorter :-DDD
I love your fall colour blanket and the shell stitch is perfect with this color repeat.
And with the sewing... I had to laugh loud. I am sooooo lazy, your advice is really important, because if I do not sew in the ends and wait for the garment/blanket to be finished, it sometimes waits very long to be finished (yarnends gaaaag)
