No, don't worry - it won't last and I'm sure it's not catching.
As the TIAS has been progressing I've noticed 'things' about the way people work. Only minor 'things' but 'things' nonetheless!!!
The first thing that sprung to my attention was that many people nowadays seem to start their tatting with CTM (continuous thread method) which obviously couldn't be done with the TIAS. The CTM while allowing the worker to avoid tying a knot at the beginning, seems (to me!) a big fiddle before you even start. Unless you know exactly how much thread you're going to need (and not many patterns tell you) there seems little point in doing this as you'll still have some thread left on the shuttles when you finish! I know some people then use the 'remains' to make little diddly things (I personally take the thread off and re-wind it back onto the ball). The TIAS involves starting with two colours which prevents the CTM totally!!
A lot of people have used an overhand knot like this to start.
Now obviously this isn't 'wrong' and people have their own reasons for starting this way but there are other ways. Personally I do prefer to knot my ends together when I start IF the item is going to be a 'wearable'. But I always use a weaver's knot which can be found here. Why a weaver's knot? Simples (does anybody from the UK follow the meerkat adverts?) - because it makes a much, much smaller knot. I then tat over the two ends too - one end in the first ring and t'other in the following element. I just sorta feel 'safer' using a knot too!!
If the item isn't going to be worn or suffer a lot of wear then I just start without a knot - here's a link for some ideas.
The one 'trick' that I've only ever used once or twice is the magic thread trick for which you can find a link here.
There are two reasons for this - the main one on which I fall at the first hurdle is planning!!!
Also I feel there is no point in using it at the start of the work as the ends can be hidden so easily. The second reason is that it does take some working out on where to put the additional threads - if you are using it as a finishing off method.
I did try it once but the ends came out a few days later!!! I know, I know that some people will say that I got the 'wrong sort' of additional thread and probably I did - BUT it's something I'm not going to risk again. Not when I know that for me it's so much easier to tie a double knot (reef knot) and then, using a self threading needle, sew the ends in!!!

Which reminds me - another tip is to add the needle onto the thread before cutting it. That way you can judge exactly how little you need!!!
The above are only my personal opinions and are a true report of how I work!!! Here endeth today's ramble!!
