Thanks for the compliments guys! Well, my boys each weigh about 10 lbs. so they fit one at a time. I bet for smaller dogs, 2 could fit perfectly.
I just got some fabric today! When I'm done I'll post the pics to see if you are interested

. They are going to have interfacing in them so they will be quite sturdy. Also, I'll post the dimensions.
Thanks again, I'm going to work on them this week and see how it goes. Wish me luck! lol
Here's a picture of Tripp after he made his bed in it
