Sharper photos
Small apertures reduce the amount of light passing through the lens, and this can lead to slow shutter speeds and long exposure times.
Any slight movement - even the vibration caused by the mirror moving inside the camera - will increase the risk of blurred pictures.
To combat this, activate your camera's Mirror Lock-up function, or shoot using Live View (where the mirror is automatically locked up) and trigger the shutter using a remote release or the camera's self-timer.
Increase the ISO to get a faster shutter speed if necessary, although you'll get the cleanest looking shots below ISO 1600.
Make a DIY a reflector
It can be challenging to ensure a small subject is evenly lit, particularly if you're using a shorter macro lens to take life-size images - the camera will need to be very close to the subject and this can limit your creative lighting options.
A simple reflector goes a long way to solving this problem. You can make your own DIY reflector using a piece of aluminum foil: screw into into a ball and then flatten it out again to create a more diffuse quality of light.
Position it on the shadow side of a subject to reveal previously hidden details.
