Yep for curves you need a 3M tape gun
, a bit pricey for a first build. You can use short pieces like Denny said, or a gluestick per Will's post works but it's not as permanent and may pull apart if you're stuffing the whole wing through the sewing machine on your first build, a bit of care and it works fine though as stated, some people use it exclusively and it washes out.
A third option I've seen, use contact cement, just brush a small amount on one side like you were using tape & let it dry to tacky then place the other side in place and burnish it down, a bit more permanent then gluestick for a first build. You may need to thin the glue since you don't want much thickness. Alternately you can use spray mount adhesive but you have to tape off the area and it's a bit messy.
