I’ve made a couple of the Knit Picks Chunky Cabled Purse and haven’t been able to find the right size canvas bag it calls for to put in it for the lining. I bought some colorful bandanas from Hobby Lobby to make the lining for them but I’m not sure how to go about it. I’m not a sewer so I really don’t know where to begin. Is there anyone that can give me a website or instructions on how to go about making a lining??
