Ensure you select the download version suited to your printer, e.g. the UK version is for A4 printers & US version is for letter size.
Before printing the templates you need to set your printer to 'actual size/1:1/100%' etc. as I have designed these templates to size, otherwise they may print off the edge. I generally create to the size of the printer paper so if you want them smaller check out the help files on the 'How to...' page.
As with all templates on this website - unless otherwise stated, black solid lines indicate cut lines & blue perforated lines are score & fold lines.
I tried making this blocks design from one sheet of card but no matter which way I attempted it, it turned out teeny! So in the end I doubled the size of the blocks & created one template that requires either two pieces of card or a 30cm (12'') square sheet, & flip the template for the second piece.
I could have easily done a template set for this fold, but that would restrict you to one size of card, & as it is so easy to achieve I typed up notes for you instead.
This is a simple shadow card with one internal layer, but it folds flat to fit into an envelope & you can even make a simple book cover for it if you want a solid front to decorate.
I have worked up a set of American sized templates with help from two friends out there in the States - as your paper sizes won't work through UK printers so I couldn't test them here, so many thanks for you help again Jane & Kathy.
