I'm finally posting the second fabric printing technique that Maia and I used a couple weeks ago (when she also printed her first day of kindergarten shirt). Tape! It was the easiest thing ever. When Maia was finished printing with round things, I asked if she wanted to try taping a design to paint. Of course the answer was yes. (Although it isn't always. Some of my suggestions fall flat.) She said she wanted to do it on a shirt for Daphne.
Here she is, taping a grid, with no design input from me. I rather thought she would tape random pieces all over the shirt, but she's been doing this grid thing more and more lately in her drawings, too. The tape is masking tape, by the way.
After she taped her grid, she painted each square a different color, mixing a couple new colors when she realized we didn't have enough different colors of fabric paint.
After the paint dried, she peeled the tape off to reveal the design. That little red splotch on the left is something she painted before putting the tape down.
She is very proud of the shirt she decorated for Daphne! As you can see in the photo at the top, it's rather too large for her still, but of course she'll grow into it.
If you want to try this with your child, all you need is masking tape and one or two colors of fabric paint (which you can purchase at most art supply or fabric stores). It's so easy! And fun. I know I'm a broken record here. I say that about most of the projects I post. But I guess those are my basic criteria. Easy and fun. Let me know if you try it!
