I have a huge stash of excellent fabrics, many Japanese and some double layered plus silks and boiled wools. It does pay to be discriminatory about what to make and to work slowly, first to adapt the pattern to suit body shape and then create a muslin. Those up and down skirts and shapeless tops, they just rely on the fabric and really not on garment fitting skill. So get the good fabric, they are worth making if sewn carefully
My home made knitteds are worth far far more than bought, I spin fine fibres into beautiful yarns eg a mix of silk, cashmere and merino or seacell and silk for short sleeved tops
I agree with crystaltips, one or two garments a year, having made a muslin. That is what I will be aiming for in future
Rockgran I have made muslins for tops from cheap linen from ebay, liked them so much that I finished them properly and wore them all summer
I also love indie patterns, the unusual, not mass produced
