You'll need:

Card board
lace trim
2 sheets of wallpaper or scrapbook paper with different patterns
white glue
hot glue and hot glue gun
5" x5" square of fabric
scissors
A smile on your face :)

First you will cut your card Board Pieces in the sizes listed below. (One size is not pictured in the photo below but will be needed and shown later on.)

2 pieces  3" x 1"
1 piece 6 1/2" x 3"
2 pieces 6 1/2" x 1"
1 piece 5 1/2" x 1"

Now assemble your bed so that it looks like the one picture here. I used my hot glue gun for this:

Pick your wall paper and cut it to a size a little bigger than the top of your bed. Add white glue over every inch of this so that the wallpaper will not buckle. I did mine this way then I used a credit card to smooth the glue completely over the top.

I laid the wallpaper over the glue and smoothed it over (you can use a clean credit card for this part too). Take a sharp hobby knife and cut the wallpaper to edge of the cardboard.

Take your second wallpaper pattern and this will go around the bottom half of the bed. It should look like the picture below when this step is completed.

Now take your lace that you will use as a bed skirt and your white glue (I used Aileen's fabric glue).  Add white glue where the two wallpaper patterns meet and add the lace along this. Remember to cut enough of this lace so that you can create a little bit of a pleated or flowing look. You do this by "pinching" some of the fabric lace together at some points. Let it dry completely. 

Now, get ready to add your second lace trim.  I used my glue gun so that I could speed this along. Remember, use it very sparingly. If you are not good at being very neat with the glue gun, your can use white glue (I did that on the first bed I made).   If you use white glue, be sure to use enough but not too much or it will come through the lace and look messy.  As you add the lace, remember to press it so that it adheres to the glue. It should cover the rough edges so that you can not see them any longer. 

Now take your cardboard piece sized 5 1/2" x 1".   This will be the pillow part of the bed. Add the glue from the hot glue gun along the bottom of one side of this piece. Then add your wallpaper to it. You will wrap the wallpaper around to the other side and then glue it in place nice and tight.

Glue the "pillow" across the bed. I added more lace because I wanted mine to look very "Girlie". Now of course, if you like your bed like this, you can stop here and enjoy. You can pose a doll on top or have pillows, dolls or even a book to make it look used or lived in. I choose instead to add a draped cover over mine. Continue to the next step to do this step.

Take your fabric and your lace trim. Add white glue around the edges and begin pressing it down so it will not come apart. Be careful because you don't want to use too much glue as it will stain the fabric! When I get to the corner, I do not cut the lace. I pinch and fold it (add a touch of glue) and continue the run like show in the 2nd picture

This is one of mine completed:

Now to drape it over the bed, you need your fingers wet (not dripping) and you need to fold your fabric in a way that it will be in the direction you want to lay it. When it dries, it will lay more easily! When it dries, get your hot glue gun and add a drop of hot glue, where you want your cover to start at. I used hot glue because white glue will bleed through (and it will take longer to dry). I then press and pinch the fabric so that it will fold nicely and look natural.

Pinch and press at the top; then add another glue drop at the bottom and pinch & press.

Then glue it around the edges and it ends up looking like this when completed:
