Ok, I used to work for a Wallpaper and Window Treatment Store, and we discontinued wallpaper books all the time, you just have to call and ask when they discontinue, and if they will put some aside for you (do go and pick them right away).
Most places are happy to give you some, they are just thrown out mostly anyhow...
Well, heres a few things you can do with them...

Gift Wrap- use it to wrap smaller presents, but you might have to use glue (or better yet, pick up a small tube of wallpaper seam adhesive, its pretty inexpensive and works great!) or 2 sided tape as most are vinyl or vinyl coated, regular tape just won't stick.

Picture Mats-One of my Favorite uses, just cut to fit the frame, and be creative, layer different textures and colors to achieve different effects.
Be careful when cutting out for the picture, I've found that using exacto blades will give you better cutting control.
Again, as most are vinyl, you want to take your time trimming and cutting.

Decorate your doll house- Are you into doll houses? You'll find that the mini prints books and texture books are great for doll houses! There is usually just enough between coordinating papers, to do a room. Alot of the books also have coordinating fabrics you can use for curtains!!

You'll find that Schools and Senior Centers are extremely happy to receive Wallpaper books for arts and crafts projects!

Here are even more tips! My thanks to my dear friend Bonnie for these!

Cottage cheese will remain fresher longer if you store it upside down in the refrigerator. This slows the effects of oxidation.

To keep milk past it's expiration date add salt. A pinch of salt in a gallon will do it. The salt slows the rate of bacteria growth.

Brown sugar will not harden if stored in the freezer.

If you freeze wild rice it will last 3-4 months compared to a week in the refrigerator.

A good trick when you go away on vacation is to place a baggie with a few ice cubes in the freezer. If a power failure occurs while you are gone and the food thaws and then refreezes you will know about it when you get home. = Ice cream container sealed in a plastic bag will stop ice crystals from forming when it is in the freezer.

Potato chip bag open again and they're all stale and yucky?? Pop them in the microwave for 30 to 60 seconds, let stand for two minutes and they'll be crispy again.

Regarding tomato paste--it seems a whole can of tomato paste is many times too much for some recipes. Suggestion: take a piece of waxed paper, putting it on a cookie sheet and putting teaspoonfuls of the leftover paste on the paper - another sheet on top and freeze this. When frozen just peel them off and put them in a baggie and when you need a tsp. or tbs. of paste you have it without opening a whole can and there is no waste--OR--put small amounts in an ice tray and then just pop them out when I need them.

Quick Whipping--A teaspoonful of cold water added to the white of an egg causes it to whip more quickly while increasing the quantity.

Moldy Fruit--What should you do with fruit with mold? Throw it away rather than simply cutting off the mold since mold on fruit goes much deeper than what appears on the fruit.

Broccoli Stalks--Don't discard the tough ends of broccoli stalks. Usethem for making soups.

Measuring Honey--Measuring honey with a spoon is easy but getting it all off the spoon is another matter--so first rub the spoon with margarine.

Dropping Cookie Dough--To get cookie dough to drop without sticking dip the spoon in milk first.

Leftover Pie Dough--Extra pie dough? Cover it with some parmesan and gruyere cheese and you'll bake a delicious appetizer--at the very same meal with your pie as dessert.

Easy Shelling--Pecans are easy to shell if they are first soaked in boiling water for 10 minutes or so. Or microwave 2 cups of pecans or brazil nuts in 1 cup of water for 5 to 6 minutes on HIGH.

Storing Cake--If you store half an apple in the container which you are storing a cake, the cake will retain its freshness.

Cheesy Apple Pie--Don't just serve cheese with apple pie, bake it right in. Spread grated sharp Cheddar on the bottom of the crust before adding the apple filling.

Outdoor cooking -- Fast Starter -- Stuff a crumbled sheet of newspaper under your coals, then roll another sheet of news paper into a cone and poke it through the coals to the paper to form a chimney. Ignite the paper. It will carry the fire into your charcoal.

Make cleaning easier--To make cook-out clean-ups easier, take a preventive step and spray the cooking grill with non-stick spray before placing the grid over the coals. Food won't stick nearly as much as it does on an untreated grid.

Juicy News--Always use tongs when turning meat on the grill. This way, you'll avoid piercing the meat, which causes it to lose its natural juices.

Poison Ivy all over the place.....how do you get rid of it???? Mix 3 pounds of salt with a gallon of soapy water; spray the solution on the plants leaves and stems. (Wonder if this really works? If you try it, please let me know)

An easy way to clean the ceiling fan is to cover your hands in a pair of old socks, and dip them in warm sudsy water and run your hand over top and bottom of each blade. Next time you clean the blades to your ceiling fan apply a thin coat of floor wax to them. It will keep future dust from clinging to them.
