Supplies needed:
Stamps,ink pads,circle punch,blending tool,bell clips,glue n gloss.

Punch out circles in white card stock n stamps the desired designs.Distress the edges with ink pads.

Apply a thick coating of glue n gloss n allow it to dry for at least 4 hours.

Once it completely dried it becomes totally transparent n the designs will be clear.Fix it to the pin with glue gun.If you don't have stamps are feel lazy to stamp,you can directly punch out pattern papers n apply glue n gloss:).The last 2 pins in the picture is made with pattern papers.In this way you can even customize it for your projects with the same pattern paper:).
Tips:If use use card stock pattern paper you can fix it directly to the pin,if it is paper then mount it on a card stock n fix it to the pin.Don't ever keep the pins one above the other,keep it fixed to a card stock otherwise it get sticked to each other.I have spoiled few of them like that:((
Happy crafting,
