I have a BAHA (bone anchored hearing aid). This is a fabulous piece of kit. I have a metal screw in the mastoid bone in my head (which incidently has to be tightened each year so I do occasionally have a screw loose),and my heading aid clips onto this screw. I hear through the bone rather than through my broken ear. This does, however, make it a little difficult wearing hats, as the hearing aid sits proud of my head and anything placed on top of it makes it whistle like a tea kettle on the boil! Lyra Hat is my solution so I’m sharing it here for other people like me. It would also be useful if you wear a ponytail.

Skills required. This hat is worked in the round from the top down. Working in the round. M1r increases, knit front and back increases. Ability to recognise and work knit and purl stitches as they appear in the work without the need for a written pattern. Casting on and off within the work.

Tension: 14st x 15 rows in pattern over 10cm x 10cm worked in the round. I used 6.5mm double pointed needles for the top and 6.5mm x 40cm circular needle for the main body of the hat. You will need to work a swatch to find the needle size that gives you the correct tension if you want your size to be correct.

You will also need 1 x 100g (100m) skein of chunkey weight yarn (the sample is knitted in Malabrigo Chunky), stitch marker for keeping track of rounds, yarn needle for sewing in ends, tape measure to determine size and placement of hole..
