not the best or easiest. A walking foot will let the top material feed at the same time as the bottom so the top fabric does not pucker or inch foward. It is well worth the investment because it can be used for any stiching on thick fabric such as with polar fleece. I use it to put on binding and other straight top stiching beside SID. The darning foot or free motion foot will require you to move the fabric yourself if the teeth are down making it hard to stay in the ditch. Also If the teeth are up then the fabric may not feed right or still pucker. Invest in a walking foot!
