Test first on scrap fabric to ensure snap size suits fabric weight. 
Handle with care. Keep away from children.

Snaps are perfect for baby bibs, diapers, childrens clothing and apparel and bags. 
Also good for soft furnishings such as cushions, quilt covers, crafts and bags. 
Instructions:

1. Select the four pieces needed for each snap - 2 caps, a stud (male) and a socket (female) section.
2. Mark placement with fabric pen and push the prong of the cap through or use an awl to make a hole in the fabric then push the prong through. 

3. Place the socket (female) over the prong with spoke side down. Place the fabric in the pliers with the outer snap cap sitting snugly in the centre of the black die of the pliers. 
4. Squeeze the handles, applying adequate pressure to compress the centre prong. 

5. Repeat the above for the stud (male) with the little gripper nodules on the stud facing down towards the prong. 

6. The snaps are correctly applied if you hear a 'snap' when closing them.
