Features1. There are 4 sizes: Extra small, small, medium, and large size, these are reusable to create more face covers. 22. It is a fast way to cut out shaped double layered face covers. Simply stack 2 coordinating fabric pieces; two times; (with right sides together) and cut around the template with a rotary cutter. There will be a total of 4 pieces; an outer set and an inner set. 33. How to use: step 1: cut 2 exteriors (1 mirrored),step 2: cut lining - cut 2cm shorter than exterior from inside of template. Then simply attach pieces together in desired format. 44. Elastic pushing tool helps you pull elastic or bias tape through face cover and allows you to push out corners if needed for multiple layers. 55. Push the threader through the face cover, insert elastic through the hole, fold it back and pull the elastic through.Easier than the old safety pin threading by far! Can also be used to straighten things if you are making a style that requires turning the face cover inside out. Helps get those corners pushed.SpecificationMaterial: plasticSize: as shownPackage List4 x templates 1 x elastic tool
