Double needle hem on jersey keeps waving back after I press it flat

You're stretching it, and reducing pressure alone rarely fixes cotton-lycra. Three things together sort it out for me.

Drop the presser foot pressure further than feels right. Most machines go much lower than people try and the feed dogs still move the fabric.

Stop pulling behind the needle. Guide it, let the feed dogs work, and if you must apply tension apply it equally in front and behind so the fabric passes through relaxed rather than stretched.

Use a stabiliser strip in the hem allowance. A 2cm strip of lightweight knit fusible along the fold gives the double needle something stable to stitch into and eliminates the wave. It slightly reduces stretch at the hem, which for a skirt is fine.

The wave returning after pressing means it was stretched while stitched, so the stitching is holding it longer than the fabric wants to be. It'll never press out permanently.

Red rot on an 1890s leather spine, consolidate it or reback it

Worth knowing why it happens so you don't repeat it with your other books. Red rot is acid deterioration in vegetable-tanned leather after a century of sulphur in the air, and it isn't contagious, but the conditions that cause it are shared. Getting the shelf away from a radiator and out of direct sun matters more than anything you brush on.

Alter three thrifted trousers myself or pay a tailor for one good pair

Split it. Hem them yourself, pay for the waists.

Hemming trousers is genuinely a beginner job. Measure, press, blind hem or hand stitch, all three done in an evening. It's the single best value alteration skill and you'll use it forever.

Taking in a tailored waistband is not. You unpick the waistband, deal with the centre back seam, the lining, the facing and usually a belt loop, then rebuild it so it doesn't look rebuilt. 45 is fair for that, and a badly done waistband is visible from across a room in a way a slightly imperfect hem is not.

At two evenings a month, learning waistbands on wool trousers you like is a recipe for three unwearable pairs and a lost autumn.
