You can purchase blank cards and envelopes at a craft store to make your own inexpensive wedding invitations. You can then buy scrapbooking supplies and other craft items, such as stamps, ribbons and dried flowers, to embellish the invitations inexpensively.
Use craft scissors to add decorative edges to handmade wedding invitations and a calligraphy pen to write on them. You can also design a wedding invitation in a desktop publishing program and print it out on blank stationery. An additional option is to use a die-cutting machine to make shapes, such as hearts or wedding bells, to glue onto handmade wedding invitations.
