When planning this little tute, it occurred to me, "Why even bother with a pillow cover, just use the form AS IS". How can you miss with natural, white, clean, pure, and contrasting trimmed out details? Come on - It's NO SEW!
When you tire of it, you can strip off the details and stuff it in a boring old pillow cover.
The first photo is the down-proof ticking pillow form anchored down on all four corners for more accurate alignement.
