I recently purchased three sheets of Katazome-shi from The Paper Place. Their library is absolutely fantasitc, sizeable, and well worth checking out. If you're interested, I bought 053, 136, and 144.

While the timing didn't work out on the intended project, I'm excited to make use of it in the future. In the short term, seeing the sheets about the apartment has motivated me to start collecting the patterns I encounter on a daily basis.
