I recently purchased a knitting book that had a beautiful blanket knitted from your scrap yarn.
The idea was to knit each row with a different string of yarn to use up your scraps. Because each row was different you could use any weight of yarn, just alternate the weights to keep a flat blanket.
If you had enough scrap yard you could do a theme like cool colors only or warm colors. Or you could group the cool colors together and gradually work towards the warm colors. Whatever your scraps allowed you to do.
Well being a new knitter and only having completed a few projects, I have a no scraps.
So I created my own version of scraps… I’m buying different skeins of yarn that are on sale. I’ll probably have enough “scraps” to knit many lap blankets for my chemo ministry. And I am leaning towards cool colors for calming blankets.
