You can tie with what I call an invisible tie. some would use clear thread. But I just take the needle and thead from the back to the front and go back down right beside where you came up. Do this 3 times and on the back tie off your thread really close and tight. Then snip your thread close to the back. I use a matching thread so it won't show. I use regular thread not yarn. So you are tieing without it showing off. Your thread should hide and not be seen unless you look real close.
