A vintage tea-cup candle> because you are the light of Her life.
Something made from tea-towels> for all the times in She came home tired and exhausted from a long day at work and slaved in the kitchen to feed you when all She really wanted was a glass of wine and a bag of chip in front of the tv.
An eye pillow> Whilst the whole Mothering Caper has been a 'joy' there has been times when a good lie down in a darkened room has been very appealing. With a flax and lavender over Her eyes hopefully that 'headache' she has had for 6 months/3 years/11 years/27 years might go away -at least for 1/2 an hour or so.
A 'hot water' wheat bag> Since you grew up and became too cool/busy for a cuddle there has been a gaping hole in Her life. Fill it with a 'hottie' made from vintage flannelette, just like your old pyjamas, it will be there for Her when you can't be.
A clutch purse> for all those times She has driven you around town no matter the time, day or night, and for all those sleepless night She had once you got your driver's license.
A patchwork quilt> life is like a patchwork quilt, lots of odd sized memories, a bit rough, a bit smooth, a bit wonky, all of it coming together to keep you warm and safe- a bit like your Mum really.
