I also use chris' "pressure-reducing" tip.  My pstat is set fairly high (about 1/4" turn away from full tightness).  As for pitcher, I use a 12oz Motta europa pitcher and steam approx 3 oz of milk for my cappuccinos (2oz epresso, 3 oz milk) .  That being said, it takes less than 10 seconds to steam the milk.  I barely dip the tip into the milk and as the milk stretches, it eventually starts rising to the point where I don't have to dip the tip any further or do any tilting (If I do try further dipping the wand or tilting, I tend to create huge bubbles).  Since the milk heats up ridiculously fast, I reach for the steam knob and begin turning it off as soon as the pitcher starts feeling hot.  I've only figured this out recently, so now I'm working on my pour.

You only have a few larger bubbles and I seem to have more than those.  I will try your lack of tipping and see if that helps me.  I have improved a lot since my class and my pours are starting to look like something.

Today I tried putting back on the stock tip instead of the chris' coffee replacement tip. I was amazed at how much the replacement tip does restrict the steam compared to the stock tip.  I did not remember it being as large a difference as it is, but I am much more comfortable at steaming now than I was when I first got my machine and replaced the tip.  I get over heated 4 oz of milk in about 10 seconds.

I did the dish soap in water trick for a while and never did get a microfoam.  I think if I am steaming lots of milk in one go, I would use the stock tip, but for doing 4oz it is just too much steam to control in too short of time.  I have turned down the pstat since I changed the tip out also. I can't imagine me trying to steam milk on the stock tip with the Pstat turned up.

hi helen, i've finally been able to get better results using the stock 4 hole tip these days by placing the wand a few degrees from vertical and placing the tip near or in the middle of the pitcher.  Since the steam is so powerful, i dont have any problem getting the milk to texture when i sink the tip in the middle after stretching.

btw i only do small amounts of milk with the stock tip.

*off to the market i go to buy some more milk*

The 4 oz of milk are steaming so fast that I am not even sinking the wand.  I am putting it a few degrees from vertical near one side to make a whirlpool and cutting the steam off as soon as I get near 100 because it is coasting to the high 140s after I stop.  I did get an ok microfoam twice this morning doing it this way with the stock tip.  I am going to see if I can handle this tip now that I have more skills than I did a year ago.  I really like foaming the milk in 10 seconds.

Day 4 on the stock tip.  

I am getting fewer larger bubbles that were marring my otherwise fine microfoams with the reduced pressure tip.  There is much more turbulence in the milk and I believe that is smashing the large bubbles better even without full steam power.   It is over in about 10 seconds and I am stopping steaming at 100 degrees even if I did not get enough stretch because 4 oz are hot enough by then to coast to 150.  So far the wand in the middle of the 12oz pitcher is doing it and I am not even really sinking it because it is heating so fast.  Just trying to control the whirlpool to make the small sucking sounds instead of the big ones it wants to make.  The 4 oz of milk are about half an inch or so below the spout and in 10 seconds the milk is above the bottom of the spout.

Easiest way to make my Oscar make nice milk is a toothpick. stick one end in one of the holes in the (stock 4-hole) steaming tip and break it off, stick the other end in the opposite hole and break it off -- voila, "pressure reducing tip".

I learned to make art with that as a helper a while ago, then went back to the full four holes and had a lot of trouble -- so I just re-restricted it, and got this first time out.   There's no particular technique I need this way, slowing things down makes it all much much easier. It's still not perfect, but it makes it a lot easier to get a reasonable pour, I only need to concentrate on pouring it right rather than dealing with uncooperative milk.

Looks good, I have the chris' pressure reducing tip but it seems to go a bit far.  Thanks for the ideas.

Is Chris' Coffee reduce-pressure tip the 2 hole tip?  I, too, find this a lot easier to use than the four hole tip.

As for pouring techniques in an 8oz cup, where does one start to pour?

Lately, I am tipping my cup at a slight angle and pouring from top to bottom.  Still a less than desired result and far from a rosetta.

No, chris has 4 holes.  I guess I need to try a 2 holer.  I was taught to tip the cup and hold it well below my waist and pour much faster than I was comfortable with.  Also she said hold the handle either at you or away (6 or 12 o'clock) that makes the design at a right angle to the handle so facing the drinker - right handed 6 and left handed 12. I also use an old dinner coffee cup (1960s) that has a nicely sloped insides and no sharp edges.  I want to find a few more like it.  Who knew it was vintage and collectible when I found it in a thrift shop.

Yours is starting to look good.  Keep trying.
