The weather can’t just become warmer with a blink of an eye (unfortunately?) and it’s cold outside, so you and your kid probably can’t be out for too long. So, there are still some fun and budget-friendly indoor ‘do-it-yourself’ activities and crafts. Here are some really cool and inexpensive cardboard creations from gorgeous castles to toys that are sure to keep your little ones entertained during those cold days while spring is only on your calendar. We hope that it would be really inspiring for you and release you from the many boxes left after Christmas or something. Enjoy!
