Step 1 - Procure a vintage glove. These are found in antique stores and boutiques for fairly reasonable prices. I've also found them on occasion in thrift stores.
Step 2 - Stuff the glove's fingers with fiberfill. Then pour in lavendar buds or your desired scent. Finish stuffing with fiberfill.
Step 3 - Hand whip the glove shut at the wrist edge with tiny stitches.
Step 4 - Embellish glove as desired with vintage corsages, millinery, pearls, costume jewelry, ribbon, tags, etc.
Step 1 - Select vintage illustrations, papers, wallpaper, sheet music, etc. to use in papercrafting the sachet. For the ones above I chose to use neoclassical papers by Dover along with vintage illustrations from a children's book of japanese poetry. It seems like an odd combo, but it really worked. Cut your papers to fit the envelope front.
Step 2 - Using spray adhesive secure your papers to the front of the envelope. Embellish as desired.
Step 3 - Fill the envelope full of lavendar buds or your chosen scent. Seal shut.
Step 4 - Presentation, presentation, presentation. Tie a small pile of sachets together with a pretty wired ribbon and tuck in some vintage millinery. Or pile the sachets into a pretty floral hatbox. Add in some bath products for a nice "pamper me" gift set.
