OK, here we go. Remember, this is just a very quick demonstration. Normally I take a few days to do these from start to finish so if you see imperfections in the paint or other details, just ignore them. :)
First, gather your supplies. Here I have a 4" terracotta pot, a saucer for the pot, a tiny pot for the chimney, paint and sealer, goop glue, rub-on transfers and my trustee dremel tool with tile cutting bit.
After soaking the pot overnight (this makes it easier to cut the door way), secure the pot so you can cut the door. I use my dremel tool with a tile cutting bit. This, to me, is the hardest part of the whole thing. Use either the dremel tool or sandpaper to smooth the edges of the door.
Put a good coat of paint of the "bottom" surface of the pot...the edge that will be sitting on the ground...to seal it. Also paint the chimney and the bottom of the "roof". Since this will be a Christmas house, I am using red and white as my colors.
When all surfaces have dried thoroughly, turn them over to paint the other side. I like to elevate the pot and roof to make painting easier. Here I am using a piece of pvc pipe for the house and an old paint can cover for the roof.
I like to put two to three coats of paint on, letting each dry thoroughly in between. I've only put one coat on this one and even then did not allow it to dry properly, just so I could get these instructions out to you. :)
Now comes the fun part! Pick out the rub on transfers that you want to put on your house. There are so many out there, it can be difficult to chose. In this case I have Christmasy ones. Rub on as per instructions. I also like to add a "molding" around my door entrance. Sometimes I will write "Welcome" over the door too. I don't have a real steady hand so that is not my most favorite thing. This is the only time I will use hand painting.
Now it's time for assembly. Dab your glue around the outer edges of the top of the pot (you can see where this is raised just a bit on the pot). CAREFULLY place the roof on, making sure it's even all around. Check carefully from all angles, otherwise you may end up with an offset roof! Use a toothpick to add glue to the tiny chimney (I also like to add hand-painted touches to this piece). Let all the pieces dry and then add several coats of clear acrylic spray to seal. Once it has thoroughly dried, it's ready to put out on your porch or in the garden to await a new occupant. :)
