Buying guide · thick fabric
Thick fabric does not need a faster motor so much as a machine that keeps pressure and feed under control. Weight is the most honest proxy at this level: a metal frame does not walk across the table.

Light leather and faux leather, with a leather needle and a walking or teflon foot, usually yes. Thick veg-tan or several layers of upholstery hide is a different class of machine entirely — that is industrial territory.
A folded jean hem can be eight layers, and the presser foot tips as it climbs, so the needle enters at an angle. Use a 110/18 jeans needle, slow right down, and level the foot with a folded scrap.
Sewing machines and overlockers swing by a hundred euros or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
