In order to complete a collage you will need to prepare some fabrics to bring to the workshop. First, background. It can be whatever you want it to be. Neutrals and low volume or something that will work with the focus of your collage. Many times, the background is made of raw edge blocks in squares and rectangles so bring at least four to five pieces that can be cut into the background. You can use a solid background as well, especially if it is a nautical or water-themed collage. It is also an option to have a pieced background and then place your collage on top of your patchwork.
Collect fabrics for your collage and by this we mean florals, novelties and other items like ribbon, lace, or yard. It is best to overpack for this part because many times you will need leaves, flowers, themed fabrics. Charm packs, layer cakes, and even jelly roll strips will work if they coordinate with your center.
