I use this A4 5-year planner book to figure my life out, especially the kids time with their dad. I really like highlighting across several days when there’s multi-day activities/plans, but it’s a total pain when things change. I wondered about using different colours of narrow washi tape but is it really moveable? Like if a weekend that’s been planned for a few months needed to change, could I really peel the tape off and stick it on a different weekend?

My daughter changed her bedsheets and I washed them at 60C. We didn’t realise there was a large lump of blutack caught up from when she put up posters until it came out of the machine. We picked off as much as we could, then I froze it - supposed to make it brittle and easy to pick off - but it didn’t make much difference. I think stretched it on a hard surface and used a smooth bladed knife to scrape off more, but we are left with this.
The internet says white vinegar or oil or ironing between sheets of kitchen roll. I don’t know what would be most effective to try first and I don’t want to make it worse! Any thoughts please?

UPDATE: I’m in the uk, and sprayed lots of WD40 on it and left it for 15 mins. This degreased the remaining residue. I then put lots of walking up liquid on it and scrubbed it together - the blue just vanished! Then a quick wash with my normal eco washing liquid but tho it has all vanished, it still smelled of oil, so it’s in for a full wash with other clothes and a stronger liquid pod. Feeling very optimistic!!
