Well done @Iminei  and @Sandra for coming up with a solution to the badly written pattern.

At this rate there will no mystery to the murder - the pattern writer will have been murdered in the sewing room by a disgruntled quilt maker with a rotary cutter.

@maliw Guild members get advance booking for the workshops - they go on general sale next Monday.

The bag is amazing. People will be too busy marvelling at the fabric to consider how the zip should have looked.

Burda have a formal jacket and waistcoat pattern that starts at 2 years, but might be a bit too detailed for dressing up.

Burda (again) have a pyjama pattern where the front of the jacket might be suitable to turn back to make lapels and this starts at 2 years.

Burda (yet again!) have a pirate costume that you might be able to adapt, but it starts at 4 years.

I'm another one who can't get twin needles to work properly for a coverstitch type hem - I always seem to get tunnelling, even after adjusting the tension. Perhaps I should try using a stabiliser, but it would probably be just as quick to get out my coverstitch machine instead.

@Efemera Thanks for this - I went shopping yesterday and got a pack for when the bank paper found at work from years ago runs out.

@b15erk I have some A4 40 gsm paper that I got for printing PDF but unfortunately the printer doesn't like it. If you want to try it for tracing, let me have your address and I will send you some.

I don't think it is worth spending too much money on the machine. Hopefully you can take a look inside and getting the foot lifting and lowering - oil and a hairdryer can be usedful to unstick stuck parts.

I would also check if the bobbin winder works as often the rubber ring perishes and the winder won't drive from the main wheel. You should be able to check this partly without a bobbin just by pushing the winder against the main wheel and seeing if the necessary bits rotate.

I have got a bag of bits and pieces from an unidentified machine of a similar era which I think include a bobbin case and some winder rings. It may be false economy to spend time trying to get them to work if they are the wrong ones, but I am happy to send you anything that might be useful and would save you money.

If you can't find one exactly the same, have a look in antique/junk shops or car boots sales for the old non-electric flat/sad irons. Alternatively, a steak weight from kitchenware places looks quite similar, but postage could be expensive.
