Anything that you feel fits into the theme of Republic Day can be made with the help of a rangoli art. The art could be creating a flag along with a message as support. Use edible items like rice, pulses, or other kitchen items for the activity. Use safe paints and colours if you are indulging the kids. Refer the picture to get an idea.

If your family members are in a high spirit of celebrating the occasion and think that decoring only the home is not enough, body art is an immediate thing to try out. As shown in the image, painting a tiny flag on the face or decorating nails will be a fun thing to do. Make sure to use only herbal colours, suitable to your skin.

Give your home the Republic Day party flavour by adding balloons to your decor idea. You only have to buy tricolour balloons and place as many as you want at your home. You can place them in bunches or singles or hanging style. Image source - quotemykaam.com

Looking to host a party on 26th January? Impress your guests with not only the decor but the food as well. Give a Republic Day touch to the presentation of the dishes. Try with snacks (idlis, dhoklas, and sandwiches), salads (using carrot, chilies, radish) and desserts (ice-cream, barfi, rasgulla). Image source - dipsdiner.com
