I recently pinned this tip to one of my Pinterest Boards

Couldn't find these mesh bags at the Dollar Store, but I did find patterned tulle and a roll of ribbon, and quickly (maybe 30 minutes?) sewed up eight sachets, and I think they are just as nice! (And so does Gibby!)
I cut the tulle ribbon 12" long -- it's about 4" wide I reckon -- folded in half and stitched 1/4" inch from each edge. This was a good excuse to tidy up a couple of shelves of our linen closet. The last few were tucked into my dresser drawers.
