I have been using black weed control/black fleece fabric for two years now and using it to suppress the weeds, while sowing seeds "through it", with great success.
For sowing things like fennel, parsnips, rainbow chard, turnips, I cut out circles about 50mm across in the fabric, and sow the seeds, where the circles have been.
For the likes of carrots, peas, beans, beetroot, raddish, lettuce, parsley etc., I cut 250mm X50mm slits in the fabric, and again sow "through" the fabric.
The main problem is anchoring the fabric to the ground, and stopping it flapping around in the wind. This can damage the young emerging seedlings.
See my previous postings re the use of black ground control fabric, about 4 weeks ago. :D
