I have absolutely no experience in flower pressing/preservation

whatsoever. Buckinghamia blossoms are quite large/thick and I expect may pose additional challenges, but they are of extreme sentimental importance to me and I desperately want to try and preserve some while they are in bloom at the moment with view to subsequently using them in or on the cover of a memorial journal as I recently lost someone very close to me.

I expect they might be similar to pressing something like a grevillea (in case anyone has any experience with these?).

Any advice, or does anyone know of any sites that deal specifically with preserving Australian native blossoms?

Thanks
