Anna, good pictures. Some hints.
I assume you are using a tripod. If not buy a cheap one.
That looks like a great hand woven carpet but you might try something a little less busy. I usually use a green file folder; Joop uses blue poster board.
Try indirect lighting by bouncing the light off a white wall or ceiling or light reflector of some sort. Unless you have professional grade stuff this will usually require the tripod for sufficent time for the exposure.
I use a "light box" made out of cardboard and painted flat white. This is the first published photo of the wunderwaffen
not pretty but it works.
PLease do not take this as a criticism of your great presentations. Keep posting them even if you do not change a thing. I use a Nikon Cool Pix camera which is a pretty simple tool and get good results with these techniques
