I personally love giving (and receiving!) gift cards. It allows the recipient the freedom to choose something they really want/need, and if you choose the store and make an effort with the presentation it can make a perfect choice.
I designed this easy gift card holder for the home reno/tool person that you might be buying for. Real Red cardstock creates the toolbox, Basic Blac cardstock creates the handle and two wide clips from the Clips Assortment (p179 current Canadian Stampin' Up! Idea Book & Catalogue) create the latches. No adhesive required – just slide them on the edge of the cardstock! (I have to admit I squealed when it worked out).
The insert is created with the Totally Tool stamp set, stamped in Basic Black and Sahara Sand. The gift card could be attached to the insert or just slid in front of it in the pocket.
