So what is stacked wound and what is cross wound? It is in this tutorial, but I will mention it here.
Look at your spool of thread.
If the thread just goes round and round, one thread right next to the last one, that is stacked wound.
Stacked wound thread is meant to come off the side, from the back of the spool to the first thread guide.

If the thread is going quickly from bottom to top and back down, crossing over the threads, that is cross wound.
Cross wound thread is meant to come off the end of the spool. If you don't have the means for this, set the spool on the floor and lead it up to the machine. (Cats love this.)
