### Another envelope formula

Hi Crafter's

As promised in my last post my formula for working out paper size for rectangle envelopes.

So here goes..........
This tut is for a rectangle card

1) Cut a piece of scrap paper or card to the size of the card you need to make the envelope for.
Click on images to get a better view.

2) Draw lines from corner to corner as shown in the above diagram.

3) Measure the distance between point "A" and point "B" add 1cm then times by 2, now measure the distance between points "C" and "D" and add this to your first figure,  this will then give you the size of the paper square that needs to be cut for your envelope.

So for instance if your card is 14cm X 24cm the measurement between point "A" and point "B" would be 10cm + 1cm = 11cm x 2 = 22cm. Add to the measurement between point "C" and "D" 7.2cm round this up to the nearest half cm 7.5cm = 22cm = 29.5cm
I find it better to round up the second measurement to the nearest half cm.

To make the envelope for the size shown above cut the paper 29.5cm square.

As with the square card
Place card on your paper as shown in diagram above.
Score paper about 3mm from the card on all four sides as shown in blue.
Then fold your envelope on the score lines.
Trim the long sides of the envelope  if necessary.

I hope this is clear and that you find it useful.
Thank you for visiting and I will see you again soon.
