Weight Sensing Tote Bag

Step 2Basting

Basting
[Edit: I later found that putting the battery pack so close to the Arduino leads to an unreliable connection as the folding motion between the two parts loosens the thread. Leave a bit more distance, two or three stitches, to prevent this from happening. ]

This is an essential step to prevent components from moving around during sewing. See the pictures for how to lay out the components for the bag. Use a reverse stitch to keep the petals in place. 

Picture 1 shows the overall layout for basting. The view is from the inside of the bag. Grey components are on the outside of the bag, and white components are on the inside of the bag. 

Picture 2 shows how to sew components with 2 petals (LED, Switch) to prevent them wobbling

Picture 3 shows how to sew components with multiple petals (Lilypad, Battery pack). 
Picture 4 shows how to place the FSR inside the strap.
