I would like to thank Gütermann and the UKQU website for asking me to test and review the Gütermann Creativ Overlock thread, Bulky – Lock 80 multicolour colour 9957. Information found here directly from their website; https://consumer.guetermann.com/en/product-finder/bulky-lock-80 . They are sold in plain or variegated multicoloured reels.

Overlockers or sergers as known in the USA, are a multi-needle machine designed to finish off the edges of fabrics with an over-locking zigzag stitch. They vary by three, four and five thread machines. Three thread machines are primarily used for overlocking where both the four and five thread machines allow for the additional secure sewing stitch from the extra needle/s.

I am lucky to own two four-thread machines. An older model Janome Harmony 9102D and a newer BabyLock Imagine BLE1AT-2 model.

I love both my overlockers and when the opportunity came up to test and play -review- I was excited. When the box arrived, I had no idea of the colour but the universe of Gütterman smiled on me with my favourite colours as a bonus. Thank you.

I was pleased to see the sample box contained five reels all at 1000 m each. As mentioned above some machines are five threads so yes you may need them all. For this review, I only needed to use three of them. However, they are available separately from £4.29 – £7.99 when I checked prices of some online retailers. The recommended retail price –RRP – is £4.65, so it is advisable that you look around. Buying for three or four reels can sound like a big financial outlay, but they do last a long while depending on project size.

Changing the thread reels on the overlockers when you need a different colour or thread type, this task scares most people and stops a few from purchasing these great machines. They can be a pain but if you take your time and practice it will become second nature. Follow your manual for the threading as each machine threads differently. My Janome needs threading in a certain order, wear as my BabyLock is threaded in any order.

A tip for threading:

Cut off the cotton at the reel end of the cone on the machine, remove the current reel /cone and add the new one. Join the thread to the old one via a small tight knot and pull that thread through the overlocker or chain off – the term given where the machine pulls the threads through, sewing a row of overlock stitches via its own power – once you have tied the other lopper threads. Please note the needle threads once they reach the needle will need to be snipped and manually fed through the eye.

About the thread, it is easy to pull apart; this is a good thing, as you want the thread to snap if it gets snagged in your machine, therefore not putting undue pressure on the machine causing damage. It is better if the seam comes apart rather than the fabric rip at the seam.

After chaining off about a meter and half I checked my machine for any noticeable increase in lint coming off the thread. All thread produces lint, but some more than others do. I was pleased to see that so far this thread did not appear to produce excessive quantities.

Towels wear out like most things, but ours always wear out around the edges, problem solved. What better way to test the thread and renew a few towels in the process. Using three threads, as I only want to overlock the edge I proceeded to overlock. The thread covered the edge nicely giving an even coverage without showing thinning of the thread.

The best thing about the variegated thread is the fact it can blend well with other colours. I needed to do a few towels, which presented a great opportunity to test the durability of the thread. Not one thread break. I did notice however, the thread was very fibrous while in the machine. This is nothing to worry about as this is normal for woolly nylon thread types. However when threading the needles this can be an issue as the fibers spread out, a good old-fashioned suck in the mouth soon sorts that issue out.

I then tested the thread through my BabyLock and again no obvious issues or excessive lint build-up. This time I chose to use some thinner fabric, some Damask and did a very narrow hem, again no issue. Having a play, I choose to do a rolled hem and made a napkin. Apart from the very rough look -user issues as I rushed it – I was overall happy with the way the thread preformed.

Overlockers are not just for edging, they are great for adding extra touches and this was an ideal thread to show off. On sample shown, I have made some tucks with fancy edging to highlight that not all stitches need to be hidden.


I had two pink towels and the one below, overlocked on my Babylock.

Some overlockers can produce a flatlock stitch, my BabyLock does however my Janome does not.

The thread reviewed is multicoloured and gives an added decorative stitch. Shown clearly in the images, sewn on stretch fabric, the front and reverse of the flatlock stitch.

Coverstitch machines are a multi needle machine designed primarily for stretch fabric to sew hems /edging incorporating the raw edge of the fabric on the reverse. They are twin or triple needle machines. This thread again preformed without issue and produced a great effect. The only issue I had was threading the two needles because of the fibres, but nothing that would stop me from using the thread on a regular basis.

Sewn on stretch fabric the front – left-hand side – and the reverse – right-hand side – of the standard twin needle coverstich, as shown in the images below.

I also had a play with my new binding attachment; see the images below for my effort.

Some more playing with my coverstitch.

Overall, the thread performed well without any major issues. The few issues I had, I feel may have been more user error rather than the thread misbehaving itself. Basically, it did what it said it would on the Gütterman website.

Thank you again to Gütermann and UKQU for asking me to review this fantastic product.
