Narrative:

Medium large transport was swbnd over gve on J75 climbing to FL350. Light transport was eastbound over gve on J42 level FL330. I failed to recognize situation when accepting handoff. I got distracted in another part of sector. C/a informed me of situation. I turned both aircraft. Medium large transport was turned west, light transport was assigned 090 degrees. I believe the primary factor to this event was the fact that this was my first day back from 10 days off. I failed to recognize that I had become may be a little rusty and I should have requested assistance on sector.
