I'm assuming the clutch disengages completely as you don't say anything about crunchy changes when driving.
How soon after you depress the clutch pedal do you pull the gear stick into 1st? While the oil in the gearbox is cold, it is thicker and will slow down the gears quickly, allowing a silent engagement. Once it is warm (and thin), the gears keep spinning for a while and if you are too quick to engage them, you'll get a crunch.
Try waiting a while before trying to engage them.
When driving, that will mean paying attention at traffic lights so you are ready to go when they change. Modern motorists in their automatic cars don't pay attention. This is just one of those little things a good Model A driver has to learn.
