Look! Martha Stewart Crafts has crepe paper flower kits for sale, they are in Michaels craft stores as well. The kits come with double-sided crepe paper, cardstock templates for cutting out petals, instructions, wire stems and floral tape. I have the Peony Kit. There are thirteen kits and they range from $13 to $15. It’s worth noting that the Martha Stewart Crafts site accepts Paypal, way too convenient. Here is what they offer: Yellow Roses, Red and Pink Tulips, Tulips and Daffodils, Irises, Red Rose Bouquet, Yellow Tulips, Rose Assortment, Dogwood Blossoms, Garden Roses, Red Roses, Daffodils, and Peonies.
Martha Stewart Crafts also sells a few assortments of double-sided crepe paper in various colors, good for making flowers.
A few years ago I used double-sided orange crepe paper to make pumpkin favors for Halloween and every few months I get an email from somebody asking if it’s still available. I bought Gloria brand double-sided crepe from Flax Art & Design in San Francisco and Alison (thanks Alison!) recently reported that she phoned Flax, 415-552-2355, and found they still carry it in a few colors for $1.80 a pack, and they will ship it to you if you want to order it over the phone. Lisa (thanks Lisa!) mentioned that she can find double-sided crepe paper at Kim’s Crane Origami Supplies, however they are moving so the online store is closed until the end of April.
If you know of another source, either online or in art supply stores, for double-sided crepe paper please do share!
