The Bundle of Joy Boy Thinlits die set by Echo Park and Sizzix includes five dies that measure between 1 3/8" x 1 7/8" and 2 7/8" x 2 1/8", as well as a storage envelope to hold them. Thinlits are wafer-thin and chemical-etched, and can be used as stencils or to emboss or cut single sheets of vellum, cardstock, paper, and metallic foil. Thinlits are designed for use in a BIGkick, Big Shot or Vagabond machine with Cutting Pads and Platform. When using an Essentials Platform or Solo Platform with Shim, an Extended Adapter or Solo Adapter is required. All items are sold separately. Thinlits may require multiple passes through the machine to cut cleanly. To make it easier to remove the cut piece from the die, place wax paper between the two before cutting.
