Here's a picture of my blanket.
Now this isn't just any blanket, mind you. At my house this is referred to as 'The duck blanket'. For reasons I'm sure you can surmise. ;)
This blanket is with me when I do most of my writing. It is very heavy, with a furry feel to it, and I like to spread it over my lap as I write. It protects my knees from my laptop. See, when I write, normally I sit cross legged on my with my laptop on my knees--It seems to be the most efficient writing posture for me.
Since I use this blanket while writing, I thought I'd show it to you. It's 21 years old and still holding strong-no holes or anything. One of the ducklings did try to detach itself from the blanket late last year, but I reattached it, I don't think it would have liked being separated from the others. ;)
