We've all seen these - sewn into medium sized clothing. These are vintage black rayon tabs - already folded in half and pressed into place. The M has been machine embroidered in white on one side of the tab only.
As you can see in the illustration, the inside of the fold shows the back of the embroidered M.
We thought these might be fun to use in altered art or assemblage. But, of course, they can still be used for their original intention - for sizing clothing!
When folded the tab measures 3/4 inch by 1/2 inch. When opened flat, it measures 1-1/2 inch by 1/2 inch.
Now, of course, you can turn it upside down and choose to use it as a W.
