Engraved glasses
Engraved glasses aren't just for wedding season. They can be transformed for any celebration, including a housewarming.
It would be a nice idea if you got some glasses engraved with a sweet message, or even quirky inside joke that they will always remember. You could get this made on a beer mug, wine glass or even coffee mug if they love to drink coffee.
A jar of cookies
There is something about cookies that just gives this warm essence. It's like you can almost smell the fresh aroma in the room when they were being baked which is why these would also make a good gift.
The jar will also show that you went the extra mile to do something nice for them. Put a cute little bow in it to make it more special.
Flowers in a vase
Flowers are also a great gift that will help turn their house into a home. It would be perfect if they woke up the next couple of mornings with a fresh vase of flowers sitting right on their table.
The flowers will be the star of the show and the vase, an extra touch. With the vase you can add some decorations too which you can buy or make some flower food for them so that the flowers can last longer.
