Supplies needed:
Color ink printer
Iron On Dark Tshirt Transfer paper (for ink-jet printers) - *there is also a version for white/light shirts too.
Scissors
Iron
Image you want to use
Plain shirt/dress/skirt, etc to put it on.
This is the image I picked from Free Pretty Things For You. (I LOOOVE her site! Adorable images, free, & great ideas - thank you for sharing with us!) I put it into PSE to resize it for a shirt. The graphic isn't perfectly sharp, but its still usable (besides my daughter moves so fast most of the time its not like anyone can tell the difference).
Once I had the image re-sized I put the transfer paper in and printed it out at best quality. I used this June Tailor Dark T-Shirt Transfer paper (they also make one for light/white shirts too).
Then I cut out around the image. Following the EASY directions on the package - I turned the iron on low (NO STEAM), took the paper backing off the image (very carefully, the vinyl type image can tear), positioned it on the shirt, layed the included parchment paper over it, and pressed down firmly for 20seconds (lifting iron up to move to get the whole image on), then for another 1-1.5 minutes ran the iron over it to make sure it was all set. That's it! DONE! So fast & easy. I spent more time searching for the right image than the entire rest of the project.
Now I waited to blog about this until AFTER she'd worn it & I had washed it. When it came to wash it I soaked it first in a bucket with white vinegar and water for a few hours - do I know if it helped, no but I thought it was worth a shot to hold the colors in. Then I turned the shirt inside out, washed on cold & hung to dry. I did have to re iron the image (w/ parchment paper) to get out the wrinkles, but it worked so well! Would I do these to sell - no. But if you need a shirt to go with a 1 time only occasion that your kids won't need again (think theme days at school or holidays) that you want something unique or custom for that is cheap, quick and easy this could be a project for you! Plus there is no sewing involved for my friends that don't know how to sew (or have time to).
**I also want to note that I also did a shirt with a ninja image for my son for his party and the red from the headband bled allover the face, so I would be careful about using red colors next to white, but a busy image like the birdy above worked great!
If you try this & it works for you let me know! Or if you need some help feel free to leave a comment - I'll see what I can do to help you!
