For V I'd love to show my collection of vintage vases, but they have already been packed and sent to the new house, so I have several vintage Velvet fabrics that I don't think I've posted about yet. The photo above shows a few cut or voided velvets.
I just love the yellow! Its from a vintage bedspread that had a bit of sun damage on one side...the perfect piece to cut for projects!
For W I have a small grouping of vintage Whitework embroidery.
And for X (wow, this one was hard!) I have a piece of vintage X-stitch and a vintage drapery fabric with a faux X-stitch design.

Be sure to stop by the Etsy Cottage Style blog to see more vintage Alphabet collections or add your own to the list!
