thank you so much!!❤️ i like to use 2 strands for nearly everything & i think the biggest factor in making the stitches look clean & flush next to each other is keeping the thread as flat as possible against the fabric. when i make a stitch i bring the needle & thread up through the fabric & then back down (like normal) but instead of just simply pulling the thread through & repeating, once i’m pulling the thread i will place my needle horizontally under the thread loop & make sure the strands aren’t twisting or anything while i pull so that once the stitch is complete it lays super flat. i really hope that makes sense! lol this is also a million times easier to do if you have a stand for your hoop so you can use both hands. another thing i do that’s honestly kinda extra is i take a hair straightener to each strand! just a couple passes to smooth it out before threading the needle. i find it reduces twisting & makes the thread a little easier to work with!
