Buttons, buttons and more buttons...

When I was a child of about 9 or 10 a great-uncle of mine gave me boxes full of buttons that he got from a clothing factory that closed down. I have been hanging on to these boxes for about thirty years (let's not get into to much detail here...) without using any of the buttons. Then about 2 years ago I got the idea to use some of the leather buttons (yes, leather buttons!) to make a place mat. I first tried to weave it together with string but that didn't work, so I ended up sewing the buttons to strips of recycled denim in such a way that it gave the impression of being weaved. This is the result:
Let me show you some more buttons from the boxes:
These have a camo appearance and my boys love them. Ideal for army play suits!Some more army-type buttons.Some coat buttons...and some more coat buttons.A few one-offs.These ones does not come from the box but was acquired somewhere along the lines... can't remember the details. The coloured ones on the left are painted leather, the small ones in the middle are denim covered and blue and pink ones on the right are painted clay.

Maybe I must open a button shop. Does anyone have some ideas on what to do with all these buttons? I would love to hear from you.
