The awl in the photo marks the first spoke that will be "cut and tucked". The spoke needs to be a spoke that is "over" the weaver on the last row.

Cut the spoke so that it's got enough length to bend over the top row and tuck under one or two rows inside. No need to cut a point unless you have difficulty getting the spoke end tucked in.

Bend the spoke over the last row of weaving, and, using the awl to hold open a space in the weaving, tuck the spoke end into the inside weaving.

You've just "cut and tuck"ed. Don't worry if some of them splinter a little. See this one? I cut a point. Points are more likely to splinter. For the rest I decided to just keep the straight edges.

Go around the basket, "cutting and tucking" as many as you can. Ouch! Be careful of your fingernails as you push the spoke ends in. Remember: ONLY the spokes that are on TOP of the last row of weaving can be cut and tucked.

When you've cut and tucked, go around the basket and trim the other spokes flush with the top edge.

Then, lash your rims bands directly on top of (not "above") this tucked and tucked top area of the basket. Your lashing will secure the rim bands into the top and it will not pull off since the bent-over spokes will hold the weaving in place.
