Bed Sheet, Circa 1980

This is a sheet.  

Last seen in March 2015, when I started crocheting a rug with 1" strips torn from said sheet.

Size Q crochet hook

 Proud to say that I completed the rug!  Used up all of the focal sheet, plus a couple rounds from a cream-colored flannel sheet, and a bit of dark teal sheet as the outer border.

How big would you say this is?

 As I was working with the teal, I was determined to use as much of it as I could.  How to know which row would be my last?  I learned a trick from my sister about working with leftover bits of yarn.  So I tried it out...

I weighed the ball at the beginning of a row; it weighed 157 grams.

After one row of crochet border, it weighed 63 grams.  So, one round used 157-63=94 grams of "yarn".  And I didn't have another 94 grams left on the ball, so I called it done at that point.

Win!
Hope that the intended recipient likes it.  These rugs-from-sheets are pretty durable--I already have a couple in my house.  I encourage everyone to try one of these!
