I love a good re purpose. I have also fallen in love with laundered drop cloth. The imperfections add interest as well as a vintage feel. I really like the cheaper brand that Walmart carries it washes super soft. This was actually the first cloth that I stenciled using the freezer paper method.
You can read about it and the Silhouette here
The pillow cover is removable and washable.
A simple envelope back using the original hemmed edge of the drop cloth as my top.
I put right sides together taking in to consideration of overlapping your two back pieces and stitched the cover 1.5 inches larger than I needed it. I turned it pressed and stitched 1.5 inches from the edge and slipped the pillow form in.
Very simple and I think it looks pretty good in this ASCP painted chair.
So glad that you stopped by,
