I started with a plain pre-made bag from Hobby Lobby, however paint & flowers can be applied to any existing bag. I like to repurpose those free bags you get at tradeshows! Some of those companies hand out great canvas bags for free - then I go & cover up their logos with artwork!
Anyways, back to the bridal bag...
Once all your circles are "edged" - stack them up large to small & put a little hand stitched "X" in the center to hold them in place. I also stacked some of my burlap & organza circles into my flower layers.
STEP 3: Paint some leaves on your bag. I used a cheapo foam stamp from the craft store and some turquoise acrylic craft paint. The reason you want to make your flowers (or at least your circles) before you paint is so that you can lay the flowers out on the bag to get the placement you like, then you can stamp your leaves accordingly.
STEP 4: Make some yo-yos out of large organza circles. (What the heck is a yo-yo? http://sewing.about.com/od/embellishment/ss/basicyoyo.htm) My organza circles were very large & I simply hand stitched a basting line about 1/2" in from the edge of the circle, then pulled it in to gather. I did not pull it in all the way, just enough so that when I placed the satin flowers on top of it, the basting thread didn't show.
STEP 5: Stack all your layers up & add some bling. I stacked my white burlap, then organza yo-yo, then my satin flower & hand stitched them together. Then I stiched a sparkley jewel in the center. Lastly, I hand stitched each flower to the bag. I didn't want the flowers to lift, or get caught on things, so I hand stitiched all the way around the bottom layer (the burlap in this case) in an "X" pattern.
I stamped a piece of muslin & used some scraps of paper & left over jewels - glue or tape it all down, punch a hole, tie a string - done!
