Eight Class I methanol masers were imaged at 44 GHz with A–configuration of the VLA providing angular resolution 0″.2. The images show a distribution of unresolved maser spots forming pairs in simple structure sources, and a distribution of pair clusters in complex sources. We found that the maser pairs are associated with hot, dense gas cores of sub–stellar masses. In complex sources the cores were found over the whole extent of the host molecular clouds.
