Question: Apparently they are white sheets, but what color is the writing (print)?
Document: The sheets are just as described. They fit well, no slipping or coming up in the corners. The color is nice and they are comfortable to sleep on.
I've flirted with getting these sheets for a while now and I finally did when I saw the queen was already selling out. Not only are they so funny and bring a smile to my face, but I find them incredibly soft. The only thing I'd mention is that the fabric is very thin, so if you're looking for that crisp white look, make sure the pillows under the cases are cripy white or double up with another solid white pillow case. Its a small damper on a very good product.
For something that I viewed as a novelty item, I am pretty happy with the quality of the sheets. They are very soft. However, they are somewhat see through so you can see any print of your mattress.
So, I bought another white sheet, sewed them together, and made a duvet out of them. Now they grace the top of my bed and I get tons of compliments from friends stopping by. I live in a small apartment where the bedroom is right off the living room; now I can leave me door open =)
I love these sheets. My husband are having a lot of fun telling each other not to cross the blue line!
Comfortable, very good quality. Sheets Look great and they wash up nicley also. Arrived within a few days. We are very happy.
These are our new favorite sheets! Super soft, very high quality, and adorable! Plus, now I can prove when my husband takes more than his half of the sheets! :)
I havent had the sheets for very long and they are already pilling up. I love the sheets but will only be able to use them a couple of days at a time... was disappointed for the price I paid for them
This was a perfect 2nd year anniversary gift for my husband who always says I'm on his side of the bed ;o) he absolutely loved it but was upset because he thought he was the only one to think of making sheets with a line down he middle. Lol :oD
Good product. I actually used this as a gag gift to my wife, but we used it. The sheets are Comfortable, and proved to my wife that she does not only sleep on &#34;half&#34; the bed. :)  Five stars means I had no issues with shipping or the product. It met my expectations and was as listed.
Answer: The writing is different shades of blue - navy/light blue.
