When I was pregnant 11 years ago, my husband and I chose to wait until birth to know if we were having a boy or girl. This forced me to decorate the baby's room in a gender-neutral way, which was my preference anyway. I was thrilled when I found a pattern for a fish applique quilt. If I'm remembering correctly, the pattern came from a book called Incredible Quilts for Kids of All Ages. Rather than make a full quilt, I made one square as a wall-hanging for the baby's room.
It still hangs in his bedroom, although I imagine its years are numbered now that my boy is just about finished with elementary school.
A few years ago I found this pattern for a night time cross stitch sampler. I made two, one for each child's bedside.
Then I tried my hand at punch needle embroidery. Most of the ready-made patterns I found were of hearts, crows, flowers, or houses, none of which excite a young boy. I had a brainstorm and made a pattern of my own:
My boy lived and breathed superheroes at the time, so this was very well-received. I didn't know much about punch-needle embroidery at the time and accidentally pulled a bunch of stitches while I framed it (oops!), but it still looks okay.
