Flat Sheets for Sleep (Mid-Town Toronto.)

Hi All, I'm really struggling with my PTSD again & not sleeping well. A new member on my Care team (the Behavioral therapist) suggested I look for flat sheet that are shades of blue, green, pink or purple to tuck over my grey couch on which I sleep (grey has been a trigger for me since my traumatic event.) I will absolutely pay it forward to wherever you request. I can travel anywhere my Presto card will take me.
I am most grateful, Erin
