Well, well, I finished it and want to share the result with you. But with only the grey sweater, I felt that it needed something else, that's why I added the crochet and the pompom border at bottom and top. But still it looked kind of none finished, that's why I added a rich pompom in the middle and attached a heart out of buttons in matching colors. Now that's what I call a pretty enriched lampshade after all, right?
And the heart of buttons turned out so nice, that I am thinking about doing some X-Mas ornaments with this technique. Could be in red color then? Or green maybe? We will see!
