@Piglin276 to make a colour switch at the edge instead of using the flat alpha colour switch you need to use the regular colour switch. MashaKnots explains this towards the end of her video on the flat alpha technique. If you are using the straight edges technique don't forget that you need to make two bf or fb knots right after each other.
this is a really cute pattern. this was the first alpha pattern i ever tried and i think it came out good for my first one 🙂 i would appreciate tips for alphas tee hee
