Most frame shops will do it BUT I paid a lot of attention to the technique and ensured that I went for something reversible and used pins - some shops used tape and said it was reversible

I also looked at Google reviews extensively, specifically for scarf framing reviews which turned out to be few and far between. It requires a different expertise to mount the silk scarf straight. Eventually I went for this IG based guy who specializes in framing scarves - cost more but made me soo much more reassured!
If you're in Singapore by any chance I can PM you the ones I seriously considered, else just generic advice
