It was deemed a hit. Her first comment on putting it on was, "it is just like on the computer". This appreciation of knit gifts must run in the family because my sister put on her socks and wore them to dinner.
She may have been tempted to wear the surprise slipper clogs but they were still a bit damp from felting and may need another cycle in the washer. Here they are before felting with my feet for reference (remember that I have freakishly small feet).
After gifting 4 knitted objects in one weekend I immediately cast on for something new when I got home. Something for me, of course, in green. More on that later this week.
