Oooooh, with a surname like “Bird” the jokes must get old by the time you’re, say, 6. Or if you married into the family, probably before the vows were even said. But I could not resist making custom “Bird” gifts for a Bird mother-to be. First, a “Birdie Bump” shirt, which involved painstakingly cutting out lettering and a bird/branch with an Exacto knife. The image is cut into freezer paper, ironed on to fabric, and then painted with acrylic paint. While the paint is still wet you carefully peel the freezer paper off. There are lots of tutorials out there on it.
With the “negatives” left over, I decided there must be a second component to the gift. Those things are too time-consuming to cut out and not use for something. So I applied those to a scrap of black fabric and painted around them, so that when those peeled off they coordinate with the maternity shirt. I sewed that onto a burp cloth.
