Photo Cards & A few questions

I've decided to make cards from my photos.  The easiest way to go is to buy 5x7 cards and add a 4x6 photo to the front and you are ready to go. Envelopes become the issue so one needs to buy sets of cards and envelopes.  These can be expensive.

After some research,  I managed to find a heavy white card stock which will serve nicely for the card base.  The photo has been trimmed to 3.5 x 4.75 inches to leave a generous border on this A2 card which is 4.25x5.5 inches. 

This requires that I have a photo I can afford to trim .25 off one side. It comes down to the composition which I will work on.  Two of these are off to my card exchange group. 

 

I am interested in finding how many folks give cards.

Do you give paper cards or electronic?

Does the cost of postage make you hesitate to give a card?

What type of occasions do you give cards for?

Do you prefer to have a card specific to the occasion?  Or will a generic card suffice for almost any occasion?

Do you have a preference between a card made with stamping and designer paper or a card like these art cards?

You can leave me a comment with any information you would like to share.  Thanks so much.
