Which cardstock should I use for wedding invitations? I don't know what yhe letter and numbers mean A7 etc.
Does "flat" mean that it is flat and not a folded card?
The cards are flat without a score (fold) line and they measure 5x7 inches.
Are these cards scored?
These are not scored, these are flat cards without a score line.
Here is the link to cards that are scored for easy folding: https://www.cutcardstock.com/collections/blankfolded5x7invitations/products/classic-crest-5x7-folded-discount-card-stock
