...or, you have something (side effect of moving your plumbing) that took a couple of months to jam up your pipes. But the fact that it's happening on both, not just hot or just cold, suggests that @BMitch is probably on the right track. Having had a "hot side only issue" that traced to a nearly plugged elbow, I feel a need to keep the idea out there when symptoms suggest a similarity.
A related possibility is that something has traveled along the pipes and actually jammed in the faucet itself. If you get full force flow from the faucet feed lines (if you disconnect them and run them into a bucket), the problem is somewhere in the faucet or diverter.
