I found in the 20 something yrs of cross stitching is try to buy your floss at the same place all the time. Experience I had... I'm almost done with a pic when I run out of a color. I call my sister. Yes she has it so she drops it off on her way to work. Weird. Both are blue. Same number, Both DMC .... BUT hers is a bluish grey. Different then mine... I bought mine at Joanns. She bought hers a Bay Variety. It happened yrs ago too when Walmart used to sell DMC... Joanns was out of a color, so I ran out to Walmart. Luckily I brought a strand with me cuz they had the same number just shades off... Now every time Joanns has their sale 5@$1, I STOCK UP..... Heres my set up.... Not too organized, but works for me. Its hard to put in order as I have 3-4 of the same colors. So split up into drawers
