Locked at home? Sew some masks! But pinning those pleats is very time cosuming. This pleating fork will speed up your process. Just put your edge in between the tines and twist. Slightly rounded to reduce pressure on the hand. Per sewist feedback, this fork is tampered and includes a corner poker and 0.5 inch graduated ruler. The Swiss Army Knife of pleating forks!
