We will need:
A flap of fabric; it took 30x50 cm for my butterfly.
Paper-based non-woven fabric the same size as the fabric.
Hot glue gun.
Velcro narrow (1 cm) to match the butterfly, 10 cm.
We are preparing a pattern. We print this pattern on an A4 sheet. Estimate at least a very conditional girth of the neck of the one to whom the butterfly is intended. At this stage, right on the pattern, you can add or remove a few centimeters, then cut out the pattern.
We apply patterns of both elements to the non-woven fabric, we pin off with pins, circle and cut without allowances.
Pins off the non-woven patterns (with the glue side to the fabric) with pins, iron with an iron, cut with an allowance of 0.5 cm.
Pins off our blanks with fabric (with the sides inwards).
Sweep on a typewriter. Leave a hole for eversion; it’s better to leave it somewhere in the middle of each element, it will be easier to turn it out. Cut the corners as close to the line on the wrong side.
We turn both elements out, sew the hole with a blind seam.
Iron the details.
We tie a butterfly. This process can take as long as sewing the butterfly itself. I use these instructions for tying butterflies from the Internet.
Now you need to make a fastener. We cut the Velcro along - so that its width becomes no more than 0.5 cm.
Glue the Velcro to the butterfly with hot glue. The part of the Velcro that is softer will be longer than the stiff. We glue the entire soft part to one part of the butterfly, cut a small piece of 1x0.5 cm from the hard part of the flypaper and glue it with hot glue to the other part of the butterfly.
Enjoy the result.
