[1] Can be cut back at the workshop when you are not busy and
stored ready for use, and one size fits all for most jobs (on door
and window frames that is) - with the added bonus that they can be
used for a multitude of other purposes when "caught out" or in an
emergency.

One size fits all?.. not a chance.
If you are making them two foot long and only 3 mm thick maybe.
If you try and fill a small gap with them you only get support on the
edges and then you can't get a secure fixing.
You need several thicknesses to do the job properly.
You obviously lack experience using them.

Dennis,

45 years as an apprenticed trained carpenter (including a 5 years
apprenticeship) with City and Guilds qualifications - along with
qualifications that allow me membership of the Incorporated British
Institute of 'Certified' Carpenters (and a few more in-between) - and I have
fitted more door frames of various types than I can remember (and one size
of folding wedge will generally do all [unless the brickies have f****ed up
of course, or you are fixing to something like a 'No-Fine' building - if you
are not sure what that is, Google the term]) and with most of my working
life in building maintenance - private and public (with some 20 odd years as
a general foreman before retirement) - and door frame fitting is the
subject of this thread is it not?

Is that enough experience for you?

Something a flimsy plastic peg cannot do!

Try it and see.
Almost any tough plastic can make a packing piece.
I have used Formica plastic off cuts in the past.

I have used almost every building material for "packing" pieces (including
'plums' in concrete to make it go further) and I must admit that a
'fag-packet' has been most useful on many occasions (even though I'm an
ardent anti-smoker) - but as usual, it's horses for courses is it not?


All the best
