Postage Help

I went to have my invitation weighed today and the post office said they will be $1.10 each to mail because they're square.

I had really wanted the $0.65 wedding cake stamp, but now would also need to put the $0.45 roses wedding stamp next to it.

My issue is the wedding cake stamp is rectangle and the roses is a square stamp, so not only don't they match in picture, but they aren't the same size. I was thinking of just spending $0.20 more for each envelope for nothing other than the look of it, and just putting 2 $0.65 wedding cake stamps so it matches.

What did you do for your invitation postage?

I did the wedding cake 65 cent stamp. On my postcards I spent the extra money and did the 45 cent roses because I really dislikes the postcard stamps. What about rotating the rose stamp so they both take up the same amount of room?
Honestly I was obsessed with the stamps and I was the only one who noticed them.

I had two .65 cents stamps but ours was 1.30

If you prefer them to be uniform how about getting personalized stamps from zazzle.com? You can pick the value of the stamp and the shape as well.
