To feed the filling into the tube, thread it onto a large dull needle. Leave only a very short tail.
Then insert it into one end of the tube.
Stroke the tube from the end of the needle until it bunches up near the head. Make sure the needle doesn’t pierce the tube. If it does, just back it off. My right hand is grabbing the bunch so it doesn’t let go, while my left strokes the tube.
Here the tube is completely bunched up on the needle.
Finally, pull the bunched tube down off the needle onto the filling. Pull the filling through until the loose end comes free, and unthread it from the needle.
Prayer: Father, help me to find You in all the details and little chores of life and craft and ministry.
