this one is simple to make. Honestly, you can pick your own size.
I can 2 stripes 8 cm on 20 cm, or do it 1 stripe- 8 cm on 30 cm. How do you like more.
Fold on half and make cuts like on the picture.
Start polling it, secure with glue to keep shape.
Attach the second piece and roll it same way.
Cut a stripe 4 cm on 12 cm, fold on half and glue sides together. Glue a ribbon or thread for hanging the ornament and poll it into the snail.
Cut a stripe 2 cm on 12 cm and roll into the tube, securing with glue, just like on picture.
Glue the tube around the top, hiding the sides of ornament.
Decorate how you want, beads, ribbons, what you like more.
