Phantom Mask

I made this pixel quilt from a pattern I created using online software at the website for the Victoria and Albert Museum. You upload your own image, chose a size, and the software generates the pattern with color shades outlined, etc. It utilizes solely squares and half-square triangles. It is very easy to use, the pattern being a lot like a counted cross-stitch pattern the quilting is actually the sheet music for the first stanza of "Music of the Night" from the "Phantom of the Opera" musical, all designed by me.
