I love old lace. And not only old lace, all kind of lace. From the last fair I got from two very nice ladies some old lace to use for my jewelry and sewing stuff! I'll show you my new treasures as soon as I start using them.
And yes, I have no problems using it, even if it is old and beautiful lace. Much better to use and love it than to let it dust in the drawers.
For the bracelet I sewed with tiny stitches the lace onto the felt ("Walkloden" in german).
I love the contrast between the roughness of the felt and the beauty of the lace as well as the colour contrast they create!
I already made some more just have to take pictures... to take to the fairs and / or to go into my shop (or to keep? I am tempted ^^).
