Stitching, Creeping, Dragging,.....anyway you name it,... it's fishing SLOOooooow!
There is no argument that these techniques are VERY affective. They simply require a different mind set from the fisherman. Stitching is a mind-bendingly slow affair, that requires a great deal of concentration and attention, as well as dedicated effort. Here are a few thoughts which may help you.
1) Location, Location, Location... As you may well know from Bill Murphy's writings, it is best to try and utilize this technique in a "known" or high confidence area. If you are going to invest the time and effort to Stitch, you might as well start in an area that will be high percentage. So your first job is to figure out where these spots are!
2) position, and boat (toob?) control. Positioning is key for you to quietly approach and cover the spot as efficiently as you can with the least amount of disturbance. Good stable boat control will help you keep a straight (not necessarily tight) angle to your bait, and not drag your bait around as you are affected by wind, wave, and current. (Many guys used to double anchor, bow into the wind.)
3) you can't fish slow enough,.... nuff said.
4) use a lot of scent
5) don't discount anything you feel,... If you think you were bit, well you probably were. Take mental note and be prepared if it occurs again. The bites range from the full -tilt -boogie, to the lollipop-lick, you just have to learn it! Your gonna swing and miss a lot!
NOTE: here is where learning to recognize the infamous "pressure bite" can be most helpful.
Way back when, the quality of our tackle made it much harder to "feel" things below the water. Nowadays with the excellence of the sensitivity of the rods, reels and lines, things are much improved. "Fingering" your line, and/or hand stitching is a lost art, and a learned skill. You will have some frustrating moments. (hours,.. days,..)
6) PATIENCE MY SON,...
PS This technique is not just for wormin' and jiggin'... A long kept secret at Casitas for 10lb+ fish was stitching a weedless (single hook) rigged, sinking, 12" Castaic Trout.
