Hello! I am a novice sewer & recently sewed my very first garments (playtime tunic & leggings). Surprisingly, all went very well (which I attribute to the excellently written Oliver + S pattern). Next, I would love to tackle the Music Box Jumper & the Sunday Brunch Jacket. One I would like to do in corduroy & the other in velveteen. After reading about both materials, my understanding (and concern) is that pressing is not recommended. I felt the key to my success when sewing the playtime tunic was due in a large part from all the pressing I did throughout the sewing process. For those of you who have sewed with these, are my concerns unfounded? Any advice on sewing with these materials would be much appreciate. Many thanks!
