This is a gorgeous set of four stitched butterfly dies in varying sizes and also features Lil' Inker Designs exclusive company invention, Dual Stitching! It's like two die sets in one! Cutting out a stitched butterfly also yields you a negative die cut with our beautiful stitching around it adding to the versatility of this set in a big way! This set also features a stitched die representing the "flight" of the butterfly. We LOVE this additional detail! It can also be used as the "hop" of a bunny with our Bunnies & Bows Die Set because of it's perfect design! The sizes are 3.5" wide, 2" w, 1.25" w and .75" w. This set is wired together unlike some of our other Dual Stitched Die Sets. We did this to keep the cost as low as possible. These dies can be VERY easily broken apart by twisting them but we recommend snipping them apart with pliers that have a cutting edge. We used mini pliers typically used for handmade jewelry which are available very inexpensively at any craft store. This helps to remove any sharp edges left behind by twisting alone.
