I just read a post on Arachne that Jean Leader and her husband, David, have released an app for iPhone and iPod Touch that provides a quick reference for about 60 individual styles of lace (with photos, of course - courtesy of The Lace Guild). More information is available at Jean's website: http://www.jeanleader.net/publications/lace-app.html
Congratulations to Jean! I have an Android phone, so won't be able to look at the new app. If anyone downloads the app and has comments, I would be very interested to hear about it.
