Purling in continental style can feel a little awkward and tricky at first (as can learning to knit or purl in any style), but it's no more difficult than forming any kind of stitch. It just takes a little bit of practice to get comfortable with the method.
To start purling in continental, hold the yarn at the front of the work and in your left hand. You can try wrapping the yarn around your index finger or around your pinkie and they around your index finger, or however feels comfortable for you.
Hold the needle with the stitches on it in your left hand and the empty needle in your right hand. Put the right hand needle into the first stitch on the needle from the back to the front and under the working yarn as well.
