Thanks Mama Jane for noticing I forgot to link to part 1 - Start here to tie dye the shirts...part 2 is appliqueing the spiders.
So the next step in the spider web shirts is to add a spider. I cut it freehand from black fabric, and I also cut corners on the applique process and just sewed the cutout on the t-shirt. I used a zig zag stitch all the way around the spiders, trying to create a hairy leg look. I also left the edge raw and frayed to add to the "hair".
