@Elnnina i have Nancy Zieman’s book as well.  Have to say it’s a bit basic and not one I reach for. 
This one is my favourite and has all sorts of info and ideas in it.

If you’re using an overlocker for knits then the usual needles in it will be fine.  There’s really no need to spend lots of money on different ones.  If you need to stabilise shoulder seams then save the selvedges from very fine linings.  Work like a charm and absolutely free.  Can’t remember where I picked up that tip.    

@So Chic yes the Jean Muir hem is a nice finish.  But doesn’t stretch so have to be careful where you use it.  I used to have a tutor that said 'one line of machine hemming says lazy.  Two lines says designer'.   

One more thing I thought about this morning Sheilago is something others on TSP have mentioned and that is  Wash Away Wonder Tape, and also Double Sided Basting Tape, and again I now have an assortment of these types of tape in my stash - so hopefully once my fabric has been washed and line dried (some of the fabrics I had from Pound Fabrics say not to tumble dry or iron), so I am waiting for continuous good weather to enable me to get this haul washed ready, as I have no way to dry this indoors - might be able to managed to dry a sweater but not yards of fabric.

Sew Essential are advertising so i presume your favourite supplier will have them on sale too 

 Oh , lots of helpful advice here. I’ve got time today, so I’ll give it a go.

Thanks Tamnymore it is always nice to hear good recommendations for on line bought fabrics.

I should have also mentioned that I indulged in yet another book 'Master the Coverstitch Machine by Johanna Lundstrom' - the cover says The complete coverstitch sewing guide, and I have to agree this is an excellent book for a novice in this field like me!!

Incidentially and changing subjects, another book by this lady Johanna Lundstrom is  'Sewing Jeans - the complete step by step guide' and I believe it is from this book that Realale found the best way for her to sew the jeans fly.

As I am so new to sewing modern day knits on modern day machines, I have equipped my sewing room accordingly, I have tape/clear elastic for sewing into the shoulder seams, I have bought some woolley nylon, some ball pointed pins, some duckbilled scissors, some ball pointed hand sewing needles and of course various packs of stretch, jersey, or ball pointed sewing machine needles, some stretch interfacing should I need it.  Now back in the 1960's/70's I am afraid I just used my ordinary dress patterns for wovens, used a 5/8" seam allowance and treated the then knits as if they were woven fabrics and it worked for me, and luckily I had no problem with popping seams and the dresses were never too tight - so I rather got away with it.  However how things have changed, now we can get patterns that are designed especially for knits, I have put on a lot of weight since those heady days of long ago, and nowadays I do not want clothes that cling to me, so I am being very cautious both with the type of knit fabrics I buy and the patterns I choose - this is a new adventure for me and one I am looking forward to very much.  Incidentally the fabric I bought from pound Fabrics was the stuff I was after - it is  double jacquard type knits so no curling edges like on the single knit fabrics - so we will see how these make up.
