Yes I have two girls so most of the times my ideas are a little bit girly. But today I found an idea on Martha stewart's site for boys so enjoyPour a small amount of quick-drying tacky glue into a jar before you start. Use a shipping tube for body of ship. Cut three fins out of corrugated cardboard, and then cut three slits into bottom of tube (slits should be as long as straight edge of each fin). Apply glue to straight edges of fins, and slide them into tube slits; secure fins with masking tape while glue dries. To make nose of ship, tie a pen to end of a piece of string. Measure circumference of tube with string, then lay string against edge of a piece of thin cardboard with pen at one end. Holding string's midpoint firmly in place, draw a half circle with pen (as you would move a compass). Cut out half circle, and then fold it into a cone; secure with glue and tape. Glue cone to top of ship, again taping to secure pieces. Once dry, remove tape. '
In the march issue, Cookie's magazine editor, Meryl Levin, describes how she made a dollhouse for her niece out of foam core board. She put graphic wrapping paper on the walls, cut clocks and pictures of out of catalogs and "framed" them with Sharpie, and her niece filled the rooms with her own toys. the result ? a personalized and fun house easy to travel with during holidays ! If you want to try this yourself, see on Cookie's blog how Meryl did it (use the diagram below as a reference).
After their travel on my computer (see previous post), my little birds need a house to rest... I had already noticed the pretty houses from Pottery Barn kids. I think they will inspire me to paint ones from Michael's with spring colors. After I will put some little home made birds ... There are models everywhere for Easter! 
A nice workshop for kids !
