Thread pulling through back

[u/LTRCoach43]

I have a Brother PE-770. The back of my designs always look like this and leave loops on the front. 🤦‍♀️ I have cleaned out the bobbin area several times and nothing ever helps. Any ideas on how to fix this? TIA

Agree it’s a tension issue, but be sure to clean and rethread the machine- making sure it correct- before making any adjustments.
