Finding application with unused items

I have some string/crochet yarn that I have.  I have a few rolls of them, in black and blue.  It is unused. It look like this:

I was thinking of using with my dyi loom.

As seen on the photo, the end result on the loom was not what I wanted.  It was fine.  I would end up with a fine cloth but I was not ready to do it.  So, I was left with the thread/yarn and no project.  Now, I have decided to use what I get for embroidery.  I think it will do the trick.  I like to take an item and used it for another purpose.  Well, I am ready to try.  If it doesn't work, I will try something else.  If I use the two together in a embroidery project, the end result will look great, I think.  I won't need to purchase embroidery floss for a long time, at least, if I don't need particuliar colour for a project.  I have a good stack of embroidery floss too, so, I don't have to worry for a while.
