Sometimes, something grabs my attention, and then I can't help seeing it everywhere. These past few weeks, I couldn't stop noticing crochet trims on pillowcases :-) (yes, I'd really like to make a set of this type of pillowcases, and no, I really don't have the time for it..)
Here are some cute examples from 1915. The one with the little violets is probably my favorite. They're taken from the book "Valeire, Anna. Crochet & Tatting Craft Book No. 1, Edgings Medallions & Insertions, with full instructions on over sixty pieces for use in lingerie & the home. St. Louis, Missouri, E.C.Spueler, c. 1915" , which you can download and/or browse for free here.
Here are some modern examples (warning: they will make you want to start crocheting right away :-):
