I have read not to press quilt seams open like a clothes seamistress would, but to press the seams together towards the darker fabric. That will help prevent the batting from bearding through the seams after quilting.

The tricky part for me is medical issues with my limbs...so I need a good iron that's not too heavy or an hour ironing session can put me out of commission for any sort of sewing for a couple days, but you also kinda want a heavy iron, see the dilemma? Any tips? I also never put water in my irons anymore. Seems to kill them quickly and make them too heavy so I have my trusty water spray bottle nearby
