Applique T-shirts?

This summer I want to start a craft project - taking plain, colourful t-shirts and put little applique desings on them, a bit like the style of Crafty couture in the top picture..

I went to see your example and the link didn't work. Please re-check and/or re-post.
Added: I think felt would be too heavy for the appliques, especially on the bottom tanktop. To me, these look like raw-edged applique with just plain cotton fabric. although they could be turned-edge. On the dress, the pockets are appliqued and decorated before the pockets are attached.
Here's some links to different ways to do applique. See which ones seem close to the look you want. For a first project, do one with just a few pieces, especially if you use fusible, because it affects the stretch of knits. Hope this gets you started.
