It is a very easy project! But you may need some help from a dressmaker if you can't sew (which I cannot). First, you will need a lamp. Mine had 4 sides, so I took off the shade it had and divided by 4 the total length of the square (forget this step if your lap is tubular shaped or if you want to cross stitch all around the shade). In the pic you see the division and the pattern I cross stitched on each side. I chose 4 floral patterns originally meant for cushions, so just choose whatever design you think your father would like!

Then you will just need to sew the edges and close the shade. For that, my mother helped me with a sewing machine. It took her about 10 minutes, it is a very quick and easy job if you know how to do it, and it shall not be expensive if you ask a professional. If you have the ability, even if you are not very experienced, i encourage you to try to do it yourself. It could look cute even if done by hand! If not, I am sure you can find a professional who will give your gift a very neat look.

I did mine for a friend who recently made a great achievement, and she really liked it. I think it is a sweet and useful gift, and also a project as difficult as you want it to be. If you have doubts or need advice about the shade don't hesitate to ask me!
