One should know all the facts before embarking on a knitting project. I confess to spontaneously asking Thing #1 and #2 if they would like mermaid blankets for the holidays (2016) — before getting all the facts or thinking it through. Thankfully, Thing #2 did not want one.
I did not heed my friend, Eileen, who had knit one for her (adult) daughter and warned me.
This was a HUGE amount of knitting. The thing is girnormous! Even though it was intended as a holiday gift, I admit it sat on the back burner more than once.
