I have been thinking about this all day and the ones I can remember (without venturing into the chaos left behind in my sewing room from making an evening dress) are:
Black faux fur cape/throw. Bought the fake fur from a Joel and Sons sale several years ago. Got as far as pinning the pattern pieces to it, deciding that the pattern wouldn't work die to the grain of the fabric, found another pattern, which was missing a piece but drafted new one, needed them to shorten it as didn't have enough fabric and decided it needed lining. Got as far as cutting out the lining when undecided i wouldn't get it finished in time for the event I was making it for.
Black silk velvet dress.a pain to hem, I can't get the neckline to lay flat and it doesn't fit right at the waist.
Turquoise chiffon smakeskin dress. Made as a wearable toil but a bit floaty for most uses
Blue and brown devore velvet dress. Not sure why abandoned. But remember zip
Pink and black demin dress. Too small. Not sure how I managed to do that as it was a pattern I had done before.
Brown and blue cotton dress. Lovely print but I wasn't happy with the pattern matching.
Brown wool jacket. Started as a semi chanel jacket. Method didn't work.
Burgundy top. Started as a recycling competition entry. Abandoned when the competition closed.
Stretch top in blue / green. Started two summers ago. Wanted to make a lot of ruffles. Decided though that it was more christmassy than summery and put aside for smore summer thing. Think it uis half sewn
Black silk velvet top. Just needs hemming?
Cotton top with skulls. Cut out but got no further.
That's 11. I really, really ought to so the cape and the velvet dress as they represent a considerable amount of money spent and would clear a lot of space. But it is more tempting to do the tops as i a have occasions to wear those.
This is all an awful waste of fabric so i must make myself finish some of them. But the husband thinks inshpuld be repairing the pockets on a pair of his jeans!
