Why non-fusible buckram? Could I use fusible?
We use non fusible because we do not need to fuse the buckram. You can
sew in fusible buckram instead if you like. It will be messy and
difficult to herringbone stitch through though if you fuse it.
Do you have to make interlined curtains wth hand pleats? Does heading tape not work with the extra bulk?
Yes you can make interlined curtains with heading tape (and we do). We
just haven't made a tutorial yet . The lighter the interlining the
easier it is to pull the heading tape into pleats.
What stiffness of buckram would you recommend? Merrick and Day have light, firm and extra firm - could you advise which of these is most suitable? Many thanks!
Not Extra Firm (very hard to hand stitch through and you will need a
strong sewing machine) we genrally use a medium stiffness buckram.
Could you ever place the buckram between the fabric and the interlining - rather than between interlining and lining- to form crisper pleats?
You probably could but it is not something we have done. We think it
might look odd and it is better keeping the form of the fabric from top
to bottom. Using a thinner interlining might be a solution to consider.
