I prefer this to any thread and over the last few years I have managed to get a nice stock of it, normally Mara 120, which I really like for sinking into the fabric, if you haven't got a good match, it doesn't matter. I know the normal sew all is slightly thicker but what I didn't realise until I was looking at the Gutermann page, was that Mara 100 Gutermann was the sew all you get in the shop and Mara 30 is the topstitch thread. In another forum that I'd picked up on a Gutermann search, there was a trail of conversation from Gutermann service department, in which they commented that Gutermann sew all was grossly overpriced, presumably at the consumer end and not theirs.
So having a big red project soon I looked for some Mara 100 on Ebay, found it, bought it, then noticed it had 5000 meters on, probably why they think the small spools are overpriced. Good job I've got some large spool holders.
