I did both EE2 and Textiles in my HSC year, so I know where you're coming from.
The important thing is to keep track of what you're doing. With creative art projects a lot of people tend to work in "stages" when inspiration/motivation strikes them, and a lot of the time this can be fine as you work best at these times anyway (so it's efficient by all definitions). However, sometimes one project gets toooo much priority and the other gets left behind in the dust - as time goes by, the "problems" with that MW become bigger and scarier in one's mind and one then avoids working on that MW - which only makes things worse.
The best thing in this situation is to have someone on your back, ensuring both projects are given an equal amount of priority. Sometimes the discrepancy can be scarily big (and this happens sometimes, I'll admit - eg materials due back at a particular amount of time, deadlines etc) but so long as you have a solid PLAN and goal for when a particular "chunk" has been completed (it's all about short-term goals and completion) you should be ok.
