Somewhere online I found a formula for making sutom envelopes. I'll put it here for you, but it's in metric measurements, so I don't know if it will be of any use top you, unless you have\can find a ruler that has metric and inperial measures on it.
I haven't tried this myself, so I don't know how well it works, but it might be worth a try
HTH anyway....
Envelope Paper Size Formula
Â
1. Measure the size of your finished card
2. Paper width should be the width of the folded card plus 3cm
3. Paper length should be the length of the folded card x 2, plus 1/2 the length again
for example
1. An A2 card is 14cm long x 11cm wide
2. 14cm + 3cm = 17cm
3. 11cm x 2 = 22cm + half of 11cm which is 5.5cm,  so it’s 22cm + 5.5cm = 27.5cm - round up to 28cm
Â
So - paper size is 17cm wide x 28cm long for an A2 size card.
Scoring Formula
This works with any size card
1. Score 1cm in from each side of the paper.
2. Subtract 3cm from width, this is the first score line across the width of the paper - for example 11cm – 3cm = 8cm, so the first score is at 8cm
3. Second Score - add card width to first score line plus .5cm - for example, 8cm (first score) + 11cm (card width) + .5cm = 19.5cm  Next score line is at 19.5cm.
Â
Score at 8cm and 19.5cm, along the length of the paper for A2 card.
