To make this into a presentable gift, and if your own artistic abilities are limited, there are two choices available. Enlist the help of an artistic friend, or rely on the uncanny abilities of your word processing program on your computer. Most programs offer borders and clip art. Arrange a pretty bordering, and perhaps some clip art that corresponds with the attributes portrayed in the acrostic. Make use of different colors for lettering and artwork.
Some people prefer to use only a border.
And this is probably best if the acrostic is of a romantic or serious nature. A wise choice in printing the acrostic is to seek out some acid free paper. Available at craft and art-supply stores, this will aid in slowing the yellowing of the finished product. This is done very inexpensively at department and discount stores. Acrostics are great gifts for people who have everything.
