Seems like a few of you are raring to give this plastic bag decals on clothing thing a go, so I thought I'd pop another example up here to give you some inspiration.
Sometimes the plastic can get a little warpy and shrivelly, so why not pick a subject that suits that effect? This is a pink lily that I put on one of my little girl's skirts. The petals are wiggly woggly anyway, so I was able to just freehand cut out and iron on bits of pink, white and green plastic bag until it looked about right, and then add little bits of black and yellow for the stamens in the middle.
It's a good idea if you are planning on adding little details to add them on top of other plastic, because you have a better chance of getting them to fuse properly to more plastic bag than to the textured material.
Lastly I want to emphasize that if in doubt that the plastic has fused well enough to the material then just keep ironing it with lots of heat and pressure. I've yet to ruin one of these by over ironing it. It would be much more frustrating to find that you'd under ironed it and it was peeling off later.
Do let me know if you have a go at this. Hope that it works out for you too :) Seems like a nice cheap easy way of getting a somewhat screenprinted look.
