Lace is very much on trend right now, particularly for evening gowns and wedding dresses - just think of Catherine Middleton's beautiful bridal frock with the long lace sleeves. And a lace wedding theme is classic and simple.
I liked these DIY lace-effect invitations I just saw on the Avie Designs Stationery Blog which you can make yourself using paper doilies. You could use them as save the date cards, will you be my bridesmaid cards, wedding invitations and thank-you cards.
The colours shown here are fairly muted, but there's nothing to stop you using brights or pastels - all depends on the shades you're using for your big day. And doilies don't have to be white either, I've seen gold and silver doilies about if you want to add a bit of bling.
You'll find the full post with full instructions here.
Thanks to Avie Designs Stationery for all the images and for this great idea!
