1. Any Indian Sweet
Karwa chauth being such an important day, the fast should always be broken with something sweet. And one of the sweetest things to break a fast with is sweet rasgullas. If you think that she wouldn't like rasgullas, you can go for gulab jamuns or kaju katlis. She will be smiling with joy to have a celebration at the end of her fast with an Indian sweet. This is a karwa chauth gift which will be a surprise to her.
2. Gift Hamper
Instead of giving one gift to her, why not give her a bunch of gifts and make the day extra special?! A gift hamper will be the most appropriate gift in that case. It will have a whole host of gifts she will love, including candies, chocolates, coffee etc. This is a gift which she will be delighted to receive and would even love to share it with you.
3. Scented Candles
And if you would like to give her something she can use, then perhaps a box of scented candles. We all know how hectic is our lives these days, and we all can use some time to relax. Scented candles are a perfect way to have that moment of relaxation. They are, in fact, considered therapeutic as their fragrance gives peace to the body. She can light one before sleeping and have a comfortable and relaxing sleep.
As a husband, you already know that Karwa Chauth is an important day for a wife. On this day, try to be a good husband and partner that she married, and more than that, be a best friend to her.
