Tshirt Laminate Floor Underlayment

We took out a fireplace downstairs and it left us with hole in our floor. One day, I want to redo the entire downstairs flooring, but that time is not now. So what to do with the floor?

I went to our local cheap house fixtures and flooring place and asked if they had any mismatched laminate flooring in the back. There was a pallet of left over laminate flooring. I found one that was super close to the piece I had brought in and so instead of paying $1.78 sq. ft for the closest match up front, I paid 50 cents a square foot for last 3 boxes that was enough to cover my hole. (Now they don't totally match, but my plan is for it to make it just a few years until I decide what I want to do with the floor and save the money to do so.)

But, you don't get the underlayment cushion when you buy out of the scrap pile. I thought we could just do without, but it made a crunchy sandy like noise when you stepped on it. So, instead of going out and buying a big roll of it on special order since I didn't need flooring with it, I cut up t-shirts and an ugly flowery t-shirt material scrap to fill the hole. Just cut to cover the majority of it, gaps were fine.

Perfect, no more crunchy noises.
