Yes I did use a pattern gotten out of one of the recent ScrollSaw Magazines. Made 2 copies of overall pattern, one to use as a guide when placing the cut pieces together and keeping them in order, the other to make numerous copies on my home printer to attach to the selected woods by using clear shelf paper with glue on one side found at Home Depot. These then are cut out to match any adjoining piece and placed on my master copy. Once completed with cut outs, creat the different depths you need with spacers if required, then round the edges to give the various contours you need. Takes time, but don’t all crafts. Sand to a finished quality. Finally glue them together and when dry, place the whole project onto a 1/4” minimum backing board and trace the outline of it to cut. Always cut short of line so it won’t be seen after you glue it to your pattern. Remove all traces of dust and finish your Intarsia with the finish of choice. Enjoy! Once you get hooked like I did there is no going back.
