May one sew clothing on Chol Hamoed?
A button fell off my Kapata, may I sew it on Chol Hamoed?
Answer:
Yes you may sew it on Chol Hamoed with a Shinuiy if you are embarrassed to walk out wearing the Kapata without the button, and you have no other Kapata available. A Shinuiy means to sew only two out of the four holes of the button, or in a loose manner.
