I have sew many hex quilts..the sizes u are talking about..really should be done by hand..the piecing will drive u crazy with a machine..because there is no quick way to do them..it will be start and stop for every piece..the sewing distance would be so short..If u plan a bigger hex then u can do them by machine easy..I personally would not do a machine hex under 4-5 inches..good luck if u do ..do it by machine..
