Here is the blanket I'm crocheting... about a month ago.
red redheart yarn crocheted blanket in progress
The ruler on the bottom right of the blanket is 18 inches long. I think I've added 2 skeins since then, so I'll take an updated picture and post it soon. Because it is so long, 2 skeins may not be very noticeable, but we'll see what it looks like!
