The term 'alternative to buttons' can be answered with two solutions: Velcro (6 letters) and SNAPS (5 letters). Velcro is a type of fastener consisting of two strips of fabric, one with tiny hooks and the other with tiny loops. When pressed together, the hooks and loops catch and hold the fabric in place. SNAPS are small metal or plastic discs that are used to fasten two pieces of fabric together. They are usually secured with a hammer or pliers. Both Velcro and SNAPS are popular alternatives to buttons, as they are easier to use and require less time to secure.
