You should tell more instructions. The velvet fabric is stretchy so it requires a certain sewing foot and needle. The fabric will roll also. Maybe use a stabilizer before sewing. Then add the felt.
Hello. Thank you for sharing this tutorial. I really love it. In fact, i already made a lot of long bow and sold it in the market. Thanks to you❤️❤️❤️. May i ask how you call this foam you put inside the velvet fabric to make it firm?
