yes, you can-- they are worth 42 cents each and the rate to Europe is 94 cents for up to one ounce. So you would two of them plus ten cents (or more )worth of other stamps.
You use three forever stamps, but would be wasting 32 cents.
After May 11, the rate goes up to 98 cents, but the forever stamps will be worth 44 cents, so 2 of them plus ten cents will still work. They make 10 cent stamps, so if you send a lot of letters to Europe you might want to get some to keep on hand.
Despite the note below, you can. MY information comes from the UPSS official web site;

Possibly the rules have changed.
No, you cannot. The lack of a face value means they are not valid under the Postal Rules of the Universal Postal Union. The post office can provide valid postage for your foreign mail.
The value of the Forever Stamp is the domestic First-Class Mail letter price in effect on the day of use.
No. The forever stamp is intended for domestic use only and doesn't meet the requirements of the Universal Postal Union for international mail.
No, you cannot. You must meet the cost for a letter which will be 98 cents. The Forever stamp is only 44 cents.
As long as you add another 66 cents in postage.
yes, indeed -- there are called "forever" because they will still be valid for postage even if rates go up.
Yes, you can use a Forever stamp on a postcard, but it's overpaying for postage.
You need $0.98 to send a letter to china, every foever stamp is $0.46 now. You can either use 3 forever stamps or use two and another 10cent stamp.
You have to use US stamps in the United States, regardless of the destination.
Yes, you can ... forever ...
Whatever the first class rate of postage is on the day you use it to mail a letter.
No you cannot use them. Forever stamps can only be used for domestic (inside the US) mail. They must have a value on them for international mail.
The word forever means forever. Theoretically, if the US remains in existence for several hundred years without interruption and the Postal Service continues under the US government, your stamp purchased in 2011 should be honored.
