Hello PACIN! This is my first post on this forum; I am new to Bark Frameworks and I am in charge of the purchasing.

We are working with a cyanotype piece that can not be exposed to alkaline environments, therefore paper buffered with calcium carbonate can't be used. The tricky part is the size; we require at least 50" x 60" and most suppliers only carry 40" x 60". Any solutions or ideas on this?

Thanks,

Vincent Ustach
