Craft activities for boys should have some pretty interesting features or you are going to lose them to other games. Things that involve animals or noise or messiness are key components to getting a boy to sit still long enough to actually work with crafts. If you can throw in hammer and nails or other tools, then they are going to be more than a little interested in the project. One of the favorites of these is making a soap box racer or a pinewood race car.
For boys, most are going to start with wood, but there are others that they might enjoy as well. Leather crafts are another of the perennial favorites, especially when they go to camp or when they belong to the Scouts. They also like clay or plaster based projects simply because they are so messy. They might like learning how to make sand candles –where they have to dig a hole in the ground and then pour in the hot wax. Anything that involves nature as well as the elements of fire and science (a liquid becoming a solid) will keep them interested.
Another type that boys might enjoy starts with pine cones, seashells or smooth surfaced rocks. From these, they can make little animals or if they are very creative, little people. All it takes is a little glue, maybe a little bit of paint or some little glued on eyes and they have something they are going to be proud of and brace yourself, but something that is going to become a gift in a very short time.
They also enjoy working on projects that involve feeding the animals or growing plants so any project you choose for them should keep those in mind. For instance, they might like to paint a special planter and then fill it with either flowers, vegetables or herb plants, watching the items that they planted grow big and strong. They might like building a bird feeder or making a string of peanut butter and bird seed pinecones. They can even create these things and then sell them to make some extra money. They are not only helping the birds in the area but they are also learning a little about marketing and other skills while they are enjoying the craft activities for boys.
