To make a basket out of drinking straws you have to start weaving by folding four straws in half and then interlinking them in the way as shown from step 1 to 3. After that weave four more straws and link the two units together as shown in step 4 and 5. Keep on repeating and linking the units.
Then using a paper clamp fold the straw ends coming out and start weaving the sides of the basket. Cut the ends of the straws at the upper edge of the basket, fold and slip them in.
Your basket is ready to hold your stuff. Enjoy crafting!
