Polarimetry is a powerful tool for studying the importance of magnetic fields in the star formation process. However, at present there are very few submm/mm polarimetry observations of large scale fields within molecular clouds. BLAST-Pol, the Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry, maps linearly polarized dust emission at 250, 350 and 500 microns; it has the unique combination of sensitivity to large scale magnetic fields, and arcminute resolution necessary to trace fields into prestellar cores and dense filaments. In this presentation I will give a brief overview of the instrument, its performance during the first BLAST-Pol science flight completed in January 2011, and plans for future flights. I will also show preliminary maps from the first science flight and explain how these maps will be used to study the relationship between large and small scale magnetic fields in molecular clouds, the degree of order in the field, and the relationship between the magnetic field structure and the morphology of filaments and cores within the clouds.
