Chenille consists of 2 types of stitches. One is a chain stitch. This is a stitch that lays flat upon the felt and acts as a border for the second type of stitch. The second type is called a loop stitch. The loop stitch ads a thick plush fill area but does not lay even on the edges. This is why the chain stitch is used. Together both the loop stitch and chain stitch complement one another and offer sharp lines, color depth and fill.
