My husband and I are planning the decorations on this evening (with the exception of the balloon inflated in the mornig) and we have many banners box of paper we use to make the place more colorful. I wonder how it's best to keep everything the night fell on us. I do not know if the color of the tape will be better? But it would be a little sticky.
