Here's the down low. I've gone through a couple of different IET (invisible elastic thread) such as Silk Worm Thread (CLEAR) and Infinity Thread V3 - and I have to say of all the kinds of IET that I have tried, PET 2.0 is the best in many areas:

-It's strong (Strong enough to lift a metal fork or glasses without breaking)
-It's VERY invisible. Not shiny like other threads. More of a flat black which is really nice.
-You get a TON of it.
-It's great for making loops with. You can keep a loop made out of PET 2.0 on your wrist the entire day while using throughout the day - and as long as you yourself don't break it by lifting something too heavy for it; the loop will be able to be used for many days without even removing the loop.

Enough about the tread, let's get on to the Million Dollar Knot. The Million Dollar Knot is basically a method for tying your own loops instead of buying them pre-made. By making your own loops you can save a ton of money because pre-made loops are pretty expensive. The method taught in the ID (Instant Download) is kind of confusing and hard to follow, especially if it's your first time working with IET. You're gonna have to watch the video a couple of times to get it down.

But don't despair! If you are not satisfied with the method taught in the ID, in the Penguins Only forum, Penguin Member - CaptainQ has posted a sticky containing a much simpler method which I and many other members have found to be much easier than the one supplied by Penguin. It's fast, easy, and makes good strong loops!

The effects taught in the ID are really cool! They are:

-Haunted Deck: A really simple haunted pack which freaks the daylights out of people! Uses a normal pack of cards.
-Crawling Fork: Make a fork crawl on the floor by using your PK powers! Really cool and simple.
-Card from Glass: A rising card effect which happens in a cup and you can be a foot away when it happens! Very cool and easy.
-Fork From Glass: Hand your spectator a cup with a fork in it. The fork slowly rises out of the cup and falls onto the floor. It all happens in their hands, and you can be like a foot away when it happens! Really cool and totally examinable.
-The Pen: Make a pen fall off the table. Not so cool, but not too bad either.

Overall, I highly recommend this product to anyone looking to get into loops. The thread is really good quality and even if you don't like the method taught in the ID, you always have a second choice in the PO Forums. My only complaint other than the method, is that you have to be REALLY careful with the thread because it's very easy to loose the end of the thread on the spool if you're not careful. But this is true with all other IET on spools. You just have to be careful when taking thread off the spool, that's all.

I only gave 4 Stars because I wasn't so fond of the method taught in the ID, but other than that - I highly recommend this product!

For those of you who don't know, this Instructional Download is on how to tie your own invisible elastic loops. Plus you get about 60 meters of invisible elastic thread in the mail.

The teaching for the loop tying is a tad bit confusing. The description says it takes five seconds but in reality it takes about 30. The tricks are mainly very good but the Haunted Deck sucks (no offense).

It is a good buy for the price.

P.S. In the PO section, some nice guy sat down and wrote his own method for tying the loops which is faster and easier.

Pros: Its really easy not that hard, the thread is really good. Thats really it.

Cons: There isnt that much bad of the cons the only bads I hate is that you can get the loop size to be accurate to your wrist size. And it takes like 2 minutes to tie one.

NOTE: NEVER USE INFINITY V2 for this system is SUCKS!!! I hate the thread now because of it. Excellent thread to use is Mesika Elastics.

This is definitely one of Penguin's best deals. High quality and thread and the ability to transform it into the most powerful tool in magic. Yes, I truly mean the most powerful. Loops are without a doubt, jawdroppers. Only problem is they are darn expensive. With this download you will learn to tie your own. After that you will have no reason not to have loops with you at all times.

I'm a big fan of Loops and so I was very happy to come across this download which teaches you how to make your own loops. It's a bit fiddly but you will save yourself a fortune in the long term.

This is a great buy. It comes with the perfect invisible elastic (which is incredibly invisible by the way) aswell as the knot technique itself.

The knot is very solid and quite simple to learn, so don't be worried about it. I'm not boyscout.

Took a little while to get the knot down, but once its down it really is a money saver. The loops are great, they have strength to do the ghost deck half way down. Totally invisible. However if this is your first time using loops, I would take a long time studying them getting used to them because they are touchy.

Penguin does a great job of teaching how to do this properly. This is nice and the package form. I thought it was a little pricey for the amount of thread. You'll need a little practice to get this one down. Be careful around crowds of younger spectators. They tend to grab at the objects.

If you're into loops, this will save you a ton of money! I found it a little tedious to tie my own loops, and just prefer the premade ones (I guess I'm just lazy). There will be a VERY SMALL know which could be visible if located in the wrong place and under the right lighting. IMO, the premade loops are a little bit better, but probably not worth the extra money. If you're just learning how to use loops, then this is for you...that way you won't be counting the dollars in your head everytime you break one!

Great stuff.
