Hi Rae and everyone,
I have learned lessons of the saleability of cards, in relation to size and the amount of decoupage, the hard way.
When I first started selling to outside of the 'family and friends' circle, about 3 years ago, I had prepared many large cards and lots of decoupage on many sizes. Believe it or not, I still have some of those cards on my hands simply because of the likely postal cost which people are acutely aware of from here. I currently run a 'bargain box' reducing them to silly prices, simply to move them and recoup a little of the expenditure ... stock is money of course!
Nowadays, for those cards I wish to put up for sale, I ensure they are mostly C6 size and on the whole keep decoupage and embellishments to a minimum, using mostly 1mm foam. Sadly this does not allow for making outstandingly beautiful cards but customers are happier and more are sold this way. I do offer just a few of larger ones just for special occasions.
I do however, allow myself the pleasure of making up some of the gorgeous kits to use as 'show cards' which usually achieve their aim of drawing attention to my market stall resulting in people at least approaching and having a browse and maybe even buying one or two of the smaller ones - a method in my little bit of madness, lol.
I am also very lucky in that there is a member of the local post office staff here who is aware of the amount of post I send and receive and will only check the odd one or two of whatever I present him with and will charge what I can only describe as an 'average' cost which I am sure is favourable to me. What it is to have friends in high places, lol.
Hugs to you all
