Like Jennerlou-hoo, I use old candle pieces to make fire starters. I take an old paper egg carton (must be paper) and stuff each cup with dryer lint. I then melt down my candles in a "double boiler" (i.e., old coffee can sitting in a pot of boiling water -- spout made by bending the can a bit). Pour the melted wax over the lint until each cup is full. Once the wax is dry, cut apart the cups. One cup is all you need to start a fire. They work great.
queenofdiy, you did an amazing job on your cosmetic bags! They are way too pretty for make-up. You could add a wrist strap and use them for evening bags. So cute.
About sewing the lining in by machine -- could you put the lining in just as if you were going to handstitch and then stitch carefully along the line of stitching on the zipper (or even use a decorative stitch or zigzag in a complementary color)? I haven't sat down at the machine and actually tried this, but in my feeble mind it seems as if it may work. Using a free-arm machine would make doing this much easier. Just a thought.
