I like to use the big bottle of clear liquid hand soap to refill the little bottles. It took two drops of the blue food coloring. I didn’t shake it up, the bottle was partly full and I just dropped in the coloring and then poured in the rest to fill the bottle. It did its own decorating…. I have a red one, too, but the picture isn’t as pretty because of the background; besides, I couldn’t make the red photo transfer.
It doesn’t take much to entertain me. 🙂
