I think a tackle box is a great idea. I started collecting vintage sewing boxes so I have a few that look like a tackle box. You know, the ones that fold out.....
Or, you could go with a tool box. I was asking for one at Christmas that was pretty large and on rollers. The bottom part was big enough that a FW would fit inside and then the upper box had lots of divisions where you could put things. It was made by Stanley. I saw them at Lowe's and Home Depot. I didn't get one because my DH said that once I got everything in it I wouldn't be able to lift it into the car. I think I could. I may still go get one.
