The catch stitch can be used for tacking or hemming lined garments. It is a zig-zagged stitch which can be worked over the raw edges, and unlike other hand sewn stitches the catch stitch is worked from left to right with the needle pointing left.

To make the catch stitch simply take a small stitch in the hem edge, with needle going in from the right to the left. Then moving to the right about 1/4"-1/2" take another stitch in the garment, again inserting the needle from the right and out to the left. Moving to the right again take another stitch in the hem edge inserting the needle from right to left. Continue this pattern crossing the stitches as you go along from left to right.

The blind catch stitch is worked in the same manner, only with the hem edge folded back about 1/2". The stitch catches back side of the hem to the back side of the garment. This stitch is great for knits because of its flexibility.
