All you'll need is:
Paper clip (optional)
Fine black felt tip or gel pen
1. First of all you need to make the tubes less tubey, as we did with the city scene, so flatten one with your hand and press firmly along the two creases.
2. Open the tube up, and line up the two creases you've just made - the flatten the tube again, making two more creases. Press firmly along these as well.
3. While the tube is still flat, use the ruler and pencil to draw a pencil line across it, 3 to 4cm (1in. to 11/2in.) from one end. This will be the height of the walls. If you are going to make more than one it would be good to vary the size and to use tubes that are different widths too.
Draw another line across, about 3cm (1in.) up from the first line. This will be one side of the roof and again the size could be altered if you want a taller, pointier roof or a flatter one.
4. Open up the tube and flatten it again, so you can see the pencil lines you've just made and it's easy to extend them. Do this one more time so the lines go right around the tube.
5. Cut down each corner to the first line you made near the bottom, and fold back the flaps firmly.
6. Cut two opposite flaps off, along the fold. Keep one spare piece for the chimneys.
7. Cut another one off too, but not right to the fold this time - leave a very small section of the flap so you can attach the roof here later.
8. Fold the remaining flap back on the second pencil line. Fold it right back so you can measure it against the other side of the roof, and cut any extra card away so both sides are roughly the same size. Then bend the roof fold the other way. Your little house is taking shape!
9. Paint the walls and roof of your house any colour you like, or you could leave it plain. Paint a spare piece of card from earlier the same colour as the walls, if you want your house to have chimneys.
10. When the paint's dry, use a fine black pen to add doors and windows to the side with the small flap. Add roof tiles too if you want, and use felt tips or paint to add any colour detail you fancy. We put flowers along the front of some of our houses and tried a rambling rose too.
For a chimney or chimneys, cut a thin strip from the spare piece of card you painted, and cut in half.
11. When you're happy with your house, brush some glue on the short flap at the front (if your glue isn't very tacky, use a paper clip to hold the card together while it dries. To make tacky glue, leave some PVA uncovered in an old jar or yogurt pot for a day or two. This should thicken it up. Very handy if you want things to stick quickly and not to slip!)
12. To add chimneys, make small cuts either side of the crease on the roof top - or just one if you only want one chimney pot. Put some glue on the bottom half of your chimney, and slot it into place. When you're happy with the height, stick the gluey part to the underside of the roof front and bend the chimney(s) into position.
Have fun creating your own houses/cottages/shops/schools! You could add a few trees from the city scene project too.
