Floating it below is very easy, you can either just float it as stated or you can use straight pins to pin it where it won't be stitched or you can use a spray adhesive. Floriani makes a really good mesh for doing t-shirts, its so soft on the skin so it won't irratate you. I've done tshirts but I do put them in the hoop or pin them to the top at the very least; you just have to be careful and not stretch them. Also becareful when using a high stitch density design because that can cause problems. I always use the layer on the bottom (cutaway) and then one on the top (WS) which really helps hold the stitches on top of the fabric. For all of you using Floriani's stabilizers, you save the label and when you have I think its ten you can go to their website and redeam them for freebees. I take the label off and then store it in the roll of stabilizer. This saves your purchase code plus another reminder of what kind of stabilizer you have .
