Q: The pattern calls for the "weave and chase" method. Could someone explain this to me in simple terms?
A: Chase weave is weaving with two pieces so that one "chases" the other. This allows you to do a continuous weave without having to split a spoke. The weavers are traditionally the same size.
Taper each piece for about 6 inches. Start weaving with one piece on one of the long sides of the base. Stop when you get to the opposite side. Now start weaving with the other piece until you catch up with piece #1. You'll soon find what works best for you - weaving until you catch up to the other piece, keeping the pieces close together and weaving over a couple of spokes with each piece, or keeping the ends on opposite sides of the basket.
When you run out, it's ended the same way as a start/stop weaving. Overlap the ends of the old weaver and new weaver for 4 spokes, hiding both ends behind a spoke.
When you reach the top of the basket, taper each end again for about 6 inches and stop them about where you started. Now weave a rim row and use this to tuck your stakes over.
