Cracked corners
DH and I just got done drywalling and mudding a bedroom in the house. The corners were a little wide, but we thought we wouldn't need the corner bracket things (no idea what they are called). So we just used some self-adhesive mesh drywall tape and a corner trowel for the mud and had a pretty thick layer that while wet looked great. But as it is drying, it is cracking. I think it's because we didn't mud underneath the tape. He thinks it's the wide gaps alone. Any ideas on what caused this or the best (and fastest) way to fix this is? Thanks!!!! Kati
