I have a fair amount of ribbon. I don't need spools or racks or some special contraption to sort and hold it all. I have mine stored in five mason jars, sorted by color. So, not bad. But then I don't usually have a problem using ribbon on my layouts. I have gotten creative with ribbon in the past, but usually, it's a border, or wrapped around a block of paper, knotted, or tied in a bow.
Ribbon is, however, fairly versatile and adds great texture to layouts.
Mix in some ribbon with your patterned paper pennants and banners.
Photo Corners were a frequent embellishment way back when. They were great for highlighting a photo or covering some photo "noise." You don't see them much anymore, but using ribbon to create a Photo Corner. . .well, there you go.
I mentioned I've wrapped a journaling card or some block of patterned paper with ribbon. I'm pretty sure I've also done a photo, but this is just a good reminder. Instead of trimming off the "deadspace" wrap ribbon over it.
A few strips of ribbon can create a border. Go diagonal (like above), keep it straight along any other edge. Embellish where all the ribbons cross. You can even add a smaller version of this border under embellishments - a grouping of flowers, a journaling card or a diecut.
Now, go unravel your ribbon and play.
