I am going to make cushions for my outdoor furniture this weekend. I chose some Sunbrella ™ outdoor fabric for them. I’d like the finished product to be luxurious and well made.
1. should I underline the cushion covers or will this impede their ability to dry out after rain?
2. are there any special things I need to know about needles, thread or tension?
3. what about zippers?
Thank you for your tips!
